Petro Trewav with other cichlids

[petro101]

I have a 60 gal tank with 1 Petrochromis Trewavasae male roughly 4". I was wondering how a single petro would do with other tank mates such as Eretmodus (goby cichlid)? Right now he is with 1 small clown pleco and 3 Neolamprologus multifasciatus which dont get bigger then 1.5" so there is plenty of hiding places where the petro cannot reach. He is quite laid back as typically he ignores everything. I've kept goby cichlids with a group of petrochromis trewav. and with a group of tropheus duboisi without issues but i'm not sure how a single petro would interact.

I've had no experience with either but I don't think a single petro would interact differently than a group would, sonic say you'd be good. The only comment I would make is that petros a group species and so if you can i would add more trews, though a 60gal is a little on the small side for a group of petros

I think that it sould be fine. I;ve kept petros for a while including the Trews and they are one of the more docile petros and do well with smaller fish. Best thing to do is try it and watch them closely. Keep them fed and tank maintained. should be fine. Danny gave you good advice for sure. A wise man.

I'll likely be upgrading the tank in a year but cant right now. They're def a lot more shy without a group. 60gal is way to small for a group which is why im just going to keep 1 for now. In the past i've kept a single petro with 4 julichromis R. and the biggest Juli had the courage to nip the petros tail while he was scraping for algae and the petro would chase. Only aggression from the petro was out of retaliation other then warning charges toward the juli (to get him out of his cave or sight). I'm guessing he probably got 1 good bite because the juli left him alone after a few cases of this happening. He would avoid the petro. The julis were always in good condition and so was the petro so it seemed quite minor, nothing like mbunas. I know the goby wont go looking for a fight so i was hoping for that response, thanks!
