Tank Cleaner w/ Crayfish?

I bought what was sold as an Australian Blue Crayfish at the pet store. It's in a 10 gallon tank with heater and filter by itself. I've been feeding it shrimp pellets, algae wafers and the occasional food scrap. However he never finishes the algae wafer and I'm getting a slight amount of algae forming on the sides and bottom of the tank. I was told at the pet store that I could put a small pleco in with him since they are armored. However he must have gotten to him while he was sleeping last night. He ate the tail off and left the rest because it was to hard to eat. Is there anything else I can put in the tank with him to take care of the algae?

Won't that make the crayfish more likely to attack the fish as well?

They are amazing cleaners but I wouldn't get them and take them back. They're notoriously difficult to acclimatise and being moved twice in a relatively short space of time could kill them. I have never kept them but heard many people talk of how they just died for no apparent reason.

Any fish in the tank will likely become food for the crawfish. Even snails are eaten by them. I had two of them years back and they would catch and eat any fish that was in there, even a fast tetra. They would wait until the tank was dark and the fish rested then grab them and eat them. Otos would suffer the same fate. I wouldn't feed him as much and stick to more stable foods like Romaine, Kale, green beans, spinach, and other veggies. they are easier to clean up and won't pollute the water if removed in less than 24 hours.

I had a common crayfish after a few molts it turned blue. I suspect that some are blue and some are greenish brown.My crayfish was like the terminator.so i would remove him from the tank and carefully snip off his pinchers.And he would leave the fish alone for awhile till he molted then the pinchers would grow back.I don't think anything is immune from crayfish attacks .you might want to keep other crayfish or just add some feeder fish but they wont keep the algae away.either keep the light off or keep the tank away from the sunshine.overfeeding sometimes causes algae. A simple pot scrubber on a stick removes algae fine.

I've heard that crayfish are territorial and no more than 1 per square foot on the tank floor.
