I"m sitting here watching my fish (just fed)... My rainbow (about 4-4.5") is kind of pushing around my ebjd (same size), but is getting faced down by my runt honduran red point (about 2" and maybe a third his weight). In the other tank, the mixteco (4") is pushing around my gt (at least an inch bigger and twice his weight). Cichlids are SO much fun to watch - but hard to figure!
