So I'd like to add an algae eater of some sort to my 44g hexagon tall corner tank. It's currently stocked with 2 angels, 4 diamond tetras, 3 lemon tetras and 3 columbian tetras. I plan on adding 5 neon tetras as soon as they grow a bit more at my LFS. I'd like to add 2 or 3 Siamese algae eaters. Do you think this is too much for my tank? I have tried an Otto cat (he died) and a rhino pleco (died too). I can see the algae on the wood and glass now. If the Siamese algae eaters are not good match, would I be crazy to put a mystery snail in? Do they even help that much with algae?
