I have this 115 gallon fish tank with no gravel and some red parrot cichlids in there. The cichlids are like 7 years old and they've kind of made a piranha like pack. I've always wanted a Lima and was wondering whether or not a lima could live with the cichlids for life. The cichlids do have some teeth and are pretty aggressive. I just don't want one party eating the other. My LFS has some limas at around 6-7 inches for about 20 dollars each.
