My cory cat just died.
I just got home from work and it was laying on the bottom of the tank. I noticed last night that it's tail was sort of pinkish and maybe it's belly as well, but I was chalking that up to the fact that I have gravel, not sand. I was looking at getting sand soon for them, but I don't understand why this one died. After looking at it post-mortem, the tail fin is pink with red bits and the stomach was pinkish. No other symptoms were observed. The only other thing I have noticed is that one of my red wag platys is swimming around with clamped fins.
Tank specs:
29 gallon
0 ammonia - liquid test
0 nitrites - liquid test
5 ppm nitrates - liquid test
Between 0 and 25 GH (I need a more accurate test) - GH, KH, and ph on strip
120 KH
7.2 pH
78 degrees F
Other inhabitants:
2 red wag platys
1 sunset wag platy
1 regular sunset platy
3 peppered cory cats
1 green cory cat
5 zebra danios
Lots of plants (growing like weeds)
2 teeny tiny snails which seem to stick around
I do a 50% water change every week (I just did one). I use a chlorine/chloramine remover when I change the water. They get fed every 2-3 days. The cory cats get Hikari mini sinking algae wafers or shrimp pellets. The rest get Hikari micro pellets or flakes supplemented with freeze dried Tubifex worms.
Could it be bacterial? I don't want to lose any of my other fish. My tank recently (3 weeks ago) finished cycling.
