At desperate times, i got my Aro to eat Hamburger, chicken (cooked) i was in shock. and many other things i found including beetles, moths, grasshoppers, worms, krill, pellets, my aro ate pleco pellets that are white... then my aro tried to eat my tiger shovelnose... then they both got sick off of lfs feeders, learnt my lesson and now i breed feeders! IT s DEF not healthy for the fish to eats lots of most of the items i listed, just desperate times call for desperate measures... Worms work well tho!
