The smaller Oto kicked the bucket this morning
I noticed it flipping upside down @ the surface last night, moved it to a quarantine tank w/ some stress coat, didn't help. Its buldgy little stomach turned a yellow-ish hue (was white).
Had a nitrite spike yesterday (7.2pH/0 Ammonia/
2ppm Nitrite/20ppm Nitrate). I did a 10% water change yesterday and a 25% today, added some more Nutrafin Cycle. I don't know what caused it, perhaps I left the piece of ketapang (almond) leaf rotting @ the bottom too long?
Any idea what caused the Oto to die, is it the nitrite? The other fish and inverts are all fine.
Some new pics (Day +1):
Did some more trimming, water cleared up nicely
Started growing a moss wall for my 9g
The evil ghost shrimp from my Spec, couldn't bring myself to flush it
RIP
of course it had to be my favorite fish
