Need suggestions for new tank

I have a 37 gallon tall tank that is sitting in my basement. I plan on setting it up but don't know what to put in it. I was thinking of getting a pair of breeding convicts but after doing some reading on them I'm unsure. I would like to see the breeding activities but don't want the fry. I know I can feed them to my larger fish but have read that a couple fry from every letter manage to survive somehow. Maybe a breeding pair of parrots???? I know most are sterile so there won't be fry to deal with. I'm open to any suggestions, doesn't have to be a breeding pair. Thanks in advance.

OK thank you. I already looked into getting the t bar convicts but it seems next to impossible to fine them. I also like the Honduras reds. The lfs normally has common convicts like black belts. Do you recommend somewhere to buy these other convicts?
