Wow, that's a huge lima! I have never seen one that big. Hopfully, my lima won't approach that length, assuming I get one. I think I am going to do some more reading before I decide on the lima, but right now, a lima seems like the most obvious choice.
However, I am still very interested in a bullhead. I really like how they are built and have heard that they are very active.
Kntrygrl4lyfe - I have my temp at 79 right now and read that I would need to lower the temp to at least 76, but I wondered if that would be a less than optimal temperature for both the bullhead (who might like it colder) and the cichlids (who might like it warmer), would I basically be sacrificing the happiness of both types of fish just to get them in the same tank? If so, I don't want to do that. If this isn't an issue, I think I am going to go the bullhead route. I just can't find any consensus or firm information on this issue and don't want to make the uneducated purchase/catch of a bullhead like I did with the rtc. If you know about this issue and could give me some feedback, I would really appreciate it.
