The tank is already set up and about a year old, and my rummies tend to stay near the bottom, which I'm pretty sure is normal for these specific tetras.david1978 said:If you dont have the tank yet it might work in a taller tank like a 29 gallon. Im just thinking the tetras would stay up higher away fron the puffer.
Not sure I follow, we have 5 Ottos in the 21 gallon low profile tank where the Pea Puffer was (for about 4 months until we moved him) and he didn't bother anyone. At all.Redshark1 said:What in particular is it about Ottos that render them immune to being bitten?
I would have thought any fish could have its fins bitten off.
