I'm looking for a "pet" cichlid. I have a 75 gallon tank. I am moderately experienced with fish (2+ decades of success) and have kept mbuna in the past. I am looking for a "pet" cichlid. I would like a fish that is bold and active, that is, one that swims around at least a moderate amount of time, rather than hiding. (I had a 4" Jack Dempsey once. He hid a lot, but I only had him about 2 months -- then I moved and found him a new home. Do you think he would have become more active given more time?) Size should be appropriate for my tank -- starting at about the size of a jewel cichlid and going on up. I once saw a Jaguar Cichlid (a female in a tank MUCH too small for her) that was very aggressive to passers-by (I was told it was female; there were no eggs or fry present). She thrashed and bit at the front glass and splashed water out. I would love a fish with that attitude -- but would never try to cause such a reaction by putting the fish in a very small tank. (I tried to buy the Jaguar Cichlid, but was told that she was already sold.) Is this typical for Jaguar Cichlids? -- What I have read about them would indicate that it is not, but I have no other experience with them. Would her extra small tank have caused her behavior? Anyway, I do like such a bold attitude. As for as other fish in the tank, whether cichlid or not, I would put others in IF it is appropriate. I am not seeking to have a fish battleground in my tank -- though aggression directed at people passing by is one thing, I don't want war in the tank. If the "pet" is too aggressive toward other fish, he will live alone. I do prefer a fish with some color, either blues/greens or reds. Lots of color is a big plus, but lots of personality/attitude with some color is most important. It doesn't have to be "fancy" -- if you tell me the "common" Firemouth is ideal for what I am seeking, I would be content. I also love fish that dig in the gravel, especially if they spend a considerable amount of time doing it. Any suggestions? Thank you so much.
