hello I'm new to this site ? I have 2 jacks and 3 sevrums ? they all seem to be at the bottom of tank ?water temp is 75 degs and everything else is okay . They just stay together at bottom . Is this normal .
Jack 1is around 4-6 in/jack 2 is 4 in /Green Sev 4 in diameter. The 2 red 3 in /the tank size is a 40 breeder.Welcome to AC
What size is your tank? That doesn't seem too outside of normal but it depends...tell us more please. What size are the fish?
Thanks/a while back I had the same group in a 60 gal/don’t have that tank anymore) they all got big and they didn’t bother each other /the I got for free /im about to purchase a 90 with a sump system /the thing is though I also have an tiger oscar I which is around 8-10 in hopefully they’ll get along , and those others you mentioned I don’t like /I like the “bad ass onesOh dear! That tank is not going to work for long with those fish. I'm sorry. I know they seemed so small & the tank so big but no! Both species grow to 8+ inches. Jacks are, like their namesake, pretty pugnacious. Severums are more mellow in comparison but they are big cichlids. I would say you can keep just 1 of any of those in a 40 breeder. Even if you have a M + F pair, somebody is going to get beat up or killed. A single cichlid can be a true wet pet, very people interactive...if they don't need to try & kill a tankmate. Think hard! This is not a long term tank or even a short term 1 with a Jack already that big. He'll soon beat the snot out of the other fish & may kill them.
I think Freshy has a severum & another big cichlid in a 75g. He has to do large water changes often. What say you Joel?
For a 40g breeder I'd tend toward a M + F pair of dwarf cichlids (apistos, rams or maybe kribensis) since you like them. & a school of mellow tetras or rasboras, maybe a smallish group of corydoras. Say 7 moderately big 1s or more of dwarf corys.
