Not that I know of. I have snails in my tank (by accident) and my cichlids eat them up like crazy. They do sell very large snails, about the size of a U.S. quarter, maybe if they can't fit in the cichlids mouth they won't eat them? I also have an electric blue crayfish, she's about 6 inches long, and she does fine with my Mbuna. She just needs a cave to hide in.
I had nerite snails about the size of a dime. The mbuna still nipped their antennae and eye stalks and constantly knocked them off the glass. They would land on their backs, and be unable to graze constantly on the algae as required to avoid starvation.
Crustaceans like shrimp and crayfish also get eaten by the fish when they molt.
I have had my crayfish since she was about 2" long. She has molted every two months almost on the dot. My fish have never bothered her, but they do help her eat her old shell after she molts it. I hate the snails I have. They breed in the filters and I can't get all of their eggs out of the substrate to elimanate them. I bought the tank used and the previous owner had sand and live plants, thus lots of snails. Even though we replaced the sand and totally cleaned out the tank, the snails continue to breed. :? I have to agree and say snails probably are not going to survive, maybe I have just been lucky with my crayfish?
Thanks for all your advice, Im not so tempted by the snails, i have a 5" Bristlenose that keeps the tank fairly algae free. I like the idea of a blue lobster/crayfish though, they are pretty cool. Im just worried it may upset the balance of the tank the fish may not like it.
I bought 3 cherry shrimp today just to see how theyd get on, but when i brought them home i decided to keep them separated from the fry so i put them in a container i usually use for fry until theyre a week or 2 old.
So theyre in the same water doing fine, I might chance letting one loose in the tank after a week or so.
I have malaysian trumpet snails in my tank....I've had them in there for about 1 1/2 yrs. My mbuna could care less about them however, most people don't care for snails. I myself don't mind them :thumb:
