like would my fish eat them? thought it would be cool if he would push it around like a toy. TIA

i dunno if he would eat them, i say buy one and give it a try, as long as they arent able to completely go in the flowerhorns mouth, i dont think they will rip them apart, but who knows

most cichlids will eat them I would bet flowerhorn will not but that they will just rip them apart I would not do it but than again they are like $5 so go for it if you do not care

theres a 3" moss ball on AB that i want but if he's gonna destroy it i rather not, im gonna grab a small one from a LFS and see how it goes

Depends on the filter bro. Like bastardfish said, most likely, it will get torn up and it might cause a problem for your filters.

It'll never work.
