Hi, I am new to the forum, and I just bought my Oto's 2 days ago. I am a little concerned with their behavior. They seem to just swim around and not really stop on any of the algae patches that I can see. I have tried putting algae wafers in but I do not know if they are actually eating them. They are in the tank with seven Tiger Barbs that are very docile. I have live plants that are working on keeping the Nitrates low and the ammonia and nitrites are at zero. They do not have "plump" stomachs but their stomachs are slightly larger than the rest of their body. The tank hovers around 78F and 80F. I know that is a lot of information but I just want to make sure that everything is up to par. I have grown to love these guys in the short time that I have had them and I don't want to lose them. In fact, right now one of them is floating around on the thermometer wire (its cute watching it sway with him). Thanks for any help you give me.
