In the beginning, I had a 7" delhezi, two 6" sens, a 8" albino sen and a10" ornate.theni got an 8" iridescent shark,two 7" Colombian driftwood catfish, an 7" azul pbass, a pair of uaru and a largish pacu.medium sized common pleco.
Surprisingly, they all get along really well. There's only been one fight and that was just after I introduced the pacu. The p bass went nuts and bashed the pacu into the side of the tank.then the pacu freaked and started biting everything. Luckily nothing major.
Apart from that seem to fine and they swim over each other and if they're being fed, sometimes straight into someone else's open mouth .
Like I said earlier, I'm not at home for the next few weeks but when I get home I'll check on them .
