fish speaker: OK...Tonight's topic is
Crenicichla...the pike cichlids.
fish speaker: I have just a few
comments about the way I want to proceed tonight.
fish speaker: I have some points that I
want to hit, but I would like to encourage participation.
fish speaker: So, if you have any
questions, comments, or if you would like to share some of your own
experiences, please feel free to let me know.
fish speaker: To start things off, I'll
tell you a few things about myself. I'm a crenicichlaholica pike
Cichlid enthusiast.
fish speaker: I have an addiction that
has me scrambling for tank space any time a new list comes out from
one of the importers.
fish speaker: That being said, I've
only kept pikes for a few years...for a reason I'll get to in a
second.
fish speaker: Crenicichla is a very
exciting genus: lots of species, with new ones being discovered, new
ones being described, and new ones being imported all the time.
fish speaker: There are some great
resources out there if you're interested in pikes. One that should
be browsed by anyone with an interest in pikes is Vinny Kutty's site,
Mostly Cichlids
fish speaker: Not only is the site full
of great information about pikes, he also has lots of information
about collecting in South America. I highly recommend it.
fish speaker: Another great resource:
other hobbyists. The exchange of experiences and sharing of
information among people who are passionate about their pikes is one
of the best ways to learn.
fish speaker: As I mentioned, I've only
kept pikes for a few years, mainly due to a myth that I want to try
to dispel. The myth deals with ...
fish speaker: Aggression.
fish speaker: I had always heard horror
stories about how aggressive pikes were...and quite frankly, I was
afraid to try them. I think this discourages lots of people from
keeping pikes, and based on my experiences, and what I've heard from
others, it's just that a myth.
fish speaker: Pikes are like other
cichlids you'll get different levels of aggression from individual
fish but most of the aggression you'll get from pikes is conspecific.
fish speaker: This is subject to a
common sense warning: most are piscivorous, so fish that are small
enough for them to swallow often are.
fish speaker: ...or, I should say, fish
that the pike THINKS are small enough to swallow...well, they'll try
fish speaker: Other large cichlids tend
to do well with them. In fact, I would say that most of mine are
less aggressive towards other cichlids than the average Central
American Cichlid. Like I said, your mileage may vary.
fish speaker: Solace (mod here, and a
member of our local aquaria club) is the person I credit for getting
me interested in trying pikes. He recommended that it was more
useful to think about pikes as 'skinny cichlids' not really anything
more dangerous than that.
fish speaker: All that being said,
pikes are not for everyone. The conspecific aggression can be
intense: I lost 2 pikes (sp. "Xingu I" or orange pikes)
when one decided to swallow the other got it all the way down, and it
killed him.
Seedy: ouch.
fish speaker: Many times, young pikes
(especially of the lugubris group we'll go through the various groups
shortly) get along fine when they are young. Then, without warning,
during the ~teenage~ years, they decide that they hate their
siblings.
fish speaker: Seedy: ...it was brutal, and tragic. A 9" pike choked on
a 6" one.

fish speaker: Again, different fish
will behave differently: I have a group of 6 cobra pikes in a
90-gallon tank soon to move to a 125. Ideally, I'll eventually have
some pairing off, and I'll keep a pair in the 125.
RustyNut: There is some kind of ironic
justice in that.....
fish speaker: (I have to admit...if he
hadn't died, I'd have really admired his ability to swallow something
that close to his own size
Glaive: Here is an example of cich1's
Crenicichla sp Venezuela wolfing down a large shrimp

fish speaker: I mentioned the cobra
pikes: The largest in the group is currently over a foot in length,
and so far they all have perfect fins no real sign of aggression in
the tank yet.
fish speaker: This is amazing to me,
since I know that I have at least 2 females in there, and most of the
fish are going into their adult coloration.
fish speaker: With most of the
lugubris-group pikes, the pikes will go through at least one major
color change before reaching maturity.
fish speaker: With the cobras,
unfortunately it changes from a nice-looking snake skin like pattern
to a more or less solid red.
fish speaker: Water parameters for
pikes. I'm always asked about this. While most are from soft water
rivers, with low pH, it's probably more important to keep the water
stable and clean, instead of worrying about hardness and pH.
Seedy: Temp?
fish speaker: pH is probably more
important for breeding than for maintenance and many of the lugubris
pikes have not been bred in aquaria.
fish speaker: Temp is also not a huge
issue for most...
fish speaker: I keep most around 80 F
fish speaker: ...but the ones from
Uruguay generally can go in an unheated tank...
fish speaker: ...they do best with at
least several months of temps around 65 F
fish speaker: Feeding can be a big
issue
fish speaker: Since many pikes haven't
been bred in captivity, many are wild-caught
fish speaker: ...and some are very
resistant to eating anything but live fish
fish speaker: hehe...Rusty's got a
point
fish speaker: I have never had to
struggle to get my pikes to take krill, but some of them will ONLY
eat krill...
RustyNut: What about live foods?
fish speaker: A few will eat anything
that i throw into the tank (convicts, pellets, convicts, etc.)
fish speaker: Live foods, such as
culls, are fine.
fish speaker: Feeders...I don't use
Seedy: How nutritious is a diet of
mostly Krill?
fish speaker: If you have a pike that
will only take live foods, it can be a struggle
RustyNut: What about gut loading the
feeders?
fish speaker: I don't think it's ideal,
Seedy: , but at least they eat.
fish speaker: Gut loading is a great
trick.
fish speaker: What I have had the best
success with is keeping the pikes with a big fish that eats
pellets...
fish speaker: ...they frequently will
learn from the other fish that pellets are actually food
fish speaker: For my picky eaters, I
try to feed a variety of frozen foods with vitamin supplements, as
well as krill
fish speaker: Any other questions about
feeding?
Glaive: do they feed better with cover
or out in the open?
fish speaker: Most of mine will attack
the food with wild abandon!
fish speaker: Only one of mine likes to
dart out from cover and retreat back to eat
RustyNut: What size food items are
best?
fish speaker: Depends on the
species/size of the pikes
Seedy: ANy idea what there feeding
habbits are like in the wild? I know they are piscivores, but do we
know much of there hunting style?
fish speaker: My foot-long cobras eat
krill that's about market shrimp size
RustyNut: 3mm pellets? 5mm?
fish speaker: Ambush predators, in
general.
DogWalker: How often do you feed yours?
RustyNut: and how much
fish speaker: The ones I have that eat
pellets will eat almost any sinking pellets
fish speaker: they don't tend to be
surface feeders
fish speaker: ...although I believe the
cobras would attack anything, anywhere...and remove lots of water
from the tank to do so
Glaive: Have you ever hand fed them?
fish speaker: I feed mine 5 days per
week...
fish speaker: I have not hand fed the
pikes...
fish speaker: (I have a midas and a Neolamprologus tetracanthus that I hand feed)
fish speaker: On the question of how
much I feed...
fish speaker: I tend to feed my pikes a
lot of food...their stomachs are nicely elastic
fish speaker: On the other hand, i have
a dwarf pike that just gets a few pellets per day
fish speaker: tonight is a fasting
night, btw
Jeff F.: mine fast Sundays thanks to a
tip from you great contributors!
RustyNut: 2 on 1 off schedule?
fish speaker: yes, 2 on 1 off
Seedy: What is the advantage of
fasting, or the danger of daily feeding?
fish speaker: ...also, since we're
running past the "normal" end time, just let me know when
to cut it off...otherwise, I might keep going for hours
RustyNut: You can go for hours
fish speaker: For me, the fasting helps
me as much as it helps the fish: feeding takes about 1.5 hours per
night.
RustyNut: Why don't we stop questioning
you and let you finish up so that we can have time for questions at
the end
Jeff F.: WOOOOOOOOW!!
fish speaker: keep the questions
coming...otherwise i'll get into something boring like "species
groups"
fish speaker: Or something
controversial like HITH
Jeff F.: Please do-
DogWalker: what are the largest and
smallest species (adult size)?
Jeff F.: And best for the inexperienced
RustyNut: C. Regani is only 2" I
noticed
fish speaker: Tough to give absolute
answers, DW...
DogWalker: (the cull disposal angle
does have its appeal)
fish speaker: for some of the larger
species, we don't yet know how large they may grow...
fish speaker: Vittata may be the
largest when all is said and done
fish speaker: ~2'
fish speaker: Best for the
inexperienced?
Seedy: What would be your suggestions
for tank sizes for the more commonly available pikes?....and what
kind of aquascaping? Any special considerations for housing them?
RustyNut: ?me okay 6-ft tank is out....
2-ft fish need 3ft wide tank minimum.... so now its at least an
8-fter!
fish speaker: Probably one of the
saxatilis, or spangled pikes
fish speaker: the spangled pikes are
smaller, easier to spawn...not picky on water quality
fish speaker: Tank size is a good issue
Jeff F.: Thanx
fish speaker: most dwarf pikes would
work in a 30 gallon tank
RustyNut:
http://www.geocities.com/NapaValley/5491/saxatilispage.html
fish speaker: although compressiceps
(green dwarf) is probably too aggressive for anything smaller than 4'
DogWalker: Since some species can live
in somewhat cooler water, are they illegal to import/sell anywhere
that you're aware of?
DogWalker: (risk of release and feral
populatins becoming established...)
fish speaker: i'm not aware of any
import restrictions, but would have to check with the importers on
that...
Jeff F.: Hawaii?
fish speaker: I don't think they really
have any awareness of the Uruguay temperatures
Seedy: Jeff, I believe they are
established in some water ways/ponds in HI
Jeff F.: I thought one of our regulars
said NO pike in HI
fish speaker: Back on the tank size
question...
fish speaker: some of the mid-sized
spangled pikes (like my menezesi pair) would work fine in a 55-75
fish speaker: Larger is always better,
like with most cichlids...
fish speaker: And the lugubris group
pikes (the big lugs), min. size of 125
fish speaker: They are fairly flexible,
so would have less "turnaround" trouble than a chunkier
cichlid
fish speaker: ...but the water quality
would be my main concern with most of these guys...
fish speaker: They produce lots of
waste...or at least they do if you feed them like i do
fish speaker: And the big lugubris
group pikes are very prone to HITH
fish speaker: While I think it's a
stress-related syndrome, keeping the water quality good is at least
the best way to keep the stress in check
fish speaker: I've currently got fry
from one pair of Crenicichla menezesi...will certainly announce if I
ever manage to get any of the big ones to spawn.
DogWalker: More PICS!
fish speaker: I need to get some new
pike-tures posted...
fish speaker: Since we're close to 10,
and i haven't eaten yet, do we want to open it up for questions?
Summary of the species groups?
Jeff F.: A nice borrowed pic!
http://www.geocities.com/napavalley/5491/proteusfemale.jpg P.S. Go
Vikings!
DogWalker: nice Jeff.
fish speaker: (action shot of 2 of my
Cr. punctata...another from uruguay
Jeff F.: Nice FS! I think this species
interest me because they've always been one of my favorite to catch!!
fish speaker: Really, Jeff? Where do
you fish for them?
RustyNut: What would you reccomend in a
125g?
Jeff F.: They're actually Northern
pike!(LOL)
fish speaker: Got it. :D
RustyNut: And tankmates?
fish speaker: (here's a bad shot of my cobra group...highly recommended)
RustyNut: Nice fish!
Jeff F.: Nice coloration.
fish speaker: At adult size, a pair of
cobras in a 125 would be about right...
fish speaker: or lenticulata...i have 4
in a 125 at the moment...probably my largest...not quite as outgoing
as the cobras
fish speaker:
(my
male Cr. menezesi)
RustyNut: wow that is some picture!
RustyNut: Tells quite the tale!
fish speaker: My most expensive pikes,
Cr. celidochilus (with the lip spots...and with gymno. tankmates)
fish speaker: That's really just the
tip of the iceberg with pikes...
fish speaker: ...but that's all I have
time for tonight. Truly enjoyed it!
RustyNut: Thank you FS
