I have a 65-gal
tank with lots of LR
and four fish, and only a few snails left from last batch I got > a year ago. I'm getting ready to order more snails, but wonder if it would be helpful to get some other cleanup critters - crabs, starfish, cuke, whatever. I've heard mixed comments on crabs - some folks advocate clawless tanks, some say certain crabs get big and attack fish, or eat snails. Even heard some negatives on some starfish.
I tend to have trouble with red/purple algae, but I just need to do PWC
's more often.
Appreciate any advice.
