motoros are pretty agressive, but only at feeding times, if they can fit something in there mouth they will eat them.... just make sure you feed them as much as you can and they should be fine.
oh man....irridiescent sharks, red finned sharks, redtail sharrk, tricolor/bala sharks, hi fin banded shark/batfiish, pisctus catfish, polypterus about 6 inches, various plecos and whiptails...most are between 4 to 6 inches...those are the lil' ones
there's also geo jur cichlids, a foot long pleco, and a 17incch marble pim/achara catfish.
I found myself thinking this morning...what would happen to my kitty fish, sorry, marbled pim if/when he gets stung? He's pretty much stationary in his spot and doesn't compete for food as he's handfed
