So far anything that moves get attacked...even floating leaves get whacked occasionally. So what algae eater last long with them.......no pleco pls as i don't like them...mine a lightly plant tank with gravel.....i got couple of tiny resident snails from the plants i bought but they r too slow to do a decent cleaning. I hate chemicals also. My algae situation is not that bad but i hate to see stuff sticking on my glass, i want them crystal clear!!
