Hi all! So I have had my red eye puffer for over a year now and he has really jumped around tanks however he finally has his own tank that I do not plan to move him from. He has been in this fluval flex 15g since Christmas, I planted and scaled it and it is probably my favorite scape in my fishroom currently. I was thinking now that the plants have grown in and there is more visual blockers if it would be possible to add another REP. I understand also that if I did do that maybe it would be a better plan to get 2 more so the aggression can be spread out. I’m just thinking because he is only one little fish in that whole ya m and the only other fish I have in there (a trio of ottos and a farrowella catfish) are also always stationary, I just want something to make it look like there is some activity. If not more puffers maybe a school of tetras (if so what kind would you suggest), however I also understand if it is not possible. I just know that that puffer stays hidden most of the day huddled in a title pocket in one of the rocks, which I know is normal behavior for them, but I really have to point him out to people. This was just a thought I had, thank in advance!
