I have a 40 gal set up with a mated pair of cichlids in it. I used rock and driftwood found at one of the rivers near our house for FREE! Got on a local fish Facebook page and hour my whole tank setup with stand, light, hanging filter, gravel for $30!! So there are some serious deals you can find for various tank sizes on a page like that. So all I really had to decide on was what fish to get, food variety, water treatment, and cleaning supplies. I probably have no more than $200 invested in my whole tank set up. However I did start out with 6 cichlids, a giant danio, and a crayfish....when two of my convicts paired up and spawned I had to remove all the other fish in the tank!
I have a jack Dempsey, 2 convicts, a jewel, a giant danio, and an electric blue crayfish. One convict died (a male) fighting for the female.
Also make sure they're all as close to the same size as possible. My jack was the smallest and he got his tail chewed up constantly till I put him in his own tank with the danio and crayfish. My jewel seems to beat up everything it goes in a tank with! Even a clown knife that's twice it's size! And my cray fish got it's to large pincers chomped off by my husbands oscars ( that's how he ended up in my tank)
So carefully research compatibility! I have 3 running tanks and still figuring out who goes best with who. This is out first time have cichlids. Love it! But it's stressful when a fish is getting picked on or you have a bully on your hands. OH! Husband has a red devil cichlid - really cool looking fish but definitely needs it's own tank in our experience so far. He chewed up one my husbands oscars that was almost twice it's size as well.
