Perhaps up to 3 other 4-5 inch ones for the time being, if he will have them. In 75 for the long term, he may not allow any others. As we all know it depends on the fish. Fortunately for me, I have a large (in excess of 1,000 gallon) cichlid pond I am setting up in a greenhouse at the school where I work. So the short answer is I would like to have 1-3 tankmates (size and temperment depending), but am prepared to move them to a larger setup if it doesn't work.
Cichlids are funny things. I have had the regular suspects never allow any tankmates, even in a 240 gallon (dovii, haitensis, Jag, etc...). But I have also had tanks with ebjd's coexisting with aggressive fish. In one tank I had an oscar and severum that owned it. They dominated a 14 inch jag and a 10 inch female dovii. That is why I love (and my wife hates) the hobby. It is fun to see what combos can work, as long as you watch it so the fish don't get hurt and have a backup plan.
With that in mind, what other similar sized cichlids would you try with this guy? I am not interested at this time in a breeding pair. Thanks.
