Four of my otocinclus catfish died, one every day for four days except for one. I checked my water paramters and got 0 ammonia, 0 nitrite, and 10 nitrate. I was going to replenish my population, but i think i have no need to do so. The remaining oto is my most active of them all, loves to swim in search of algae, and the most independent. She never was a part of the group of otocinclus and preffered to be with her own people, the zebra danios. She even picked up some of their bad habits, nipping and playing with the other... sane oto catfish. I'm not sure what caused the deaths, and should i still replenish my otocinclus? She's definately not lonely.

I guess if not she's happy, but after a while she might realize the other ottos aren't there. Who knows, maybe she hung out with them at night or something, and she'd want some more friends.
