i would never put a fish it my bucket im sure it would die. besides that, like the other guy said, you shouldnt have algae. change your res every week. if light gets thru put black garbage bag or something that blocks light over it. light is the reason for algae growth. temps i think would be ok though. from my reading, algae eaters prefer about 77F but im sure you could lower it a bit for your plants. i know for a fact from reading and experience, you want hydro 68-72ish F i've gotten away with 74-76 however i did get a little root rot. go any higher than that and your just asking for root rot problems. most people i know seem to like 70.
