Has anyone had this problem and know the cause or what I can do?
I have a 30 hex with the following
2 - angel
2 - german rams
2 - dwarf gouramis (are these guys the problem?)
3 - cories
1 - apple snail
0 ammonia, 0 nitrite, 30 ppm nitrate or lower
I've had the tank set up for about 4-5 months. The angels have been in about 3 1/2 months. I've never had any problems with them, they have always ate well and are always at the front of the tank when I get home, very active.
BUT, lately one has been hiding. I mean this one has been swimming under spots that seem too small for it and just sits there. It's been like this for almost a week. It's not coming up for food at feeding time. It shows no visual signs of disease and still swims occasionally, I caught it last night doing so and then back to hiding.
Can anyone help me understand this?
