hello forum, I have a 44 gal I bought used real cheap. So far I have an african butterfly and a medium sized dinosaur eel (polypterus palmas) I have a couple a questions to throw out there. First I know some of the habits of the african butterfly but mine seems pretty lethargic even for this kind of fish. I expected him to swim around a bit at night but it doesn't seem like he is...any thoughts? second I was wondering about adding a mid level semi aggressive swimmer like a needle fish or something. I don't think it would be overstocked at that point. I also plan on adding a bristelnose pleco in the future when he actually has some algae to eat. thanks for the responses (if there are any).
