cleaner shrimp too big?

[knutcracker]

my cleaner shrimp has molted a dozen times in a few months. It is now 4 inches not counting antenna and will compete with fish for food. Will he cause trouble? should I replace with a smaller one along with a coral banded shrimp? The tank is only 26g and the shrimp is the biggest creature. Thanks.

I don't think your "cleaner shrimp" will be a problem. It is nowhere near as big a risk as a coral banded shrimp (Stenopus hispidus) which is really very aggressive and known to eat small fish and other shrimp.
