I was so concerned about my new fish in my aquarium, as I have a huge catfish in there, an algea eater (Plecos) and he is a bully! However, when I fed them this morning, I was able to count eleven of the thirteen, so that was really encouraging. I noted that they all have great hiding places, so they obviously know what is going on in there and they may start to band together to gang up on the bully. I hope they do anyway. They are a bunch of neon tetras. I bought 13 of them last Thursday. Neons have done well with the bully before, and I had about 8 of them last time I bought them and they lasted about 2 years, so the fish place said I did good with them (they died of old age).
