dont get cons.even though they are one of the easiest to breed,i would go with jack dempseys.very prolific,and extremely beautiful.its not as easy to tell them apart but you would be much happier with them instead of cons.i actually have both,and suprisingly,the jds mate more often than the cons,with bigger batches.the jds are just as protective as the cons,but with more muscle to back them up too.
