I have some blue/green alage in my 125 Discus tank, I was going to try treating with Marycin but my LFS said I shouldn't. He told me there were some larger alage eatting shrimp that he could get me that would work. Has anyone heard of these River Shrimp that would be large enough not to be bothered by Discus and could tolerate the higher water temp and a ph of 6.5? I'm thinking he's all wet.
