well i have a fire shrimp in my 14 gallon bio cube. i bought him cause i wanted him to clean the fish and he looks very cool. its been maybe a month or two since i had him and he doesnt clean the fish and his personality isnt the best he always is in the back where i cant see him accept for feedings. will it get a long with a cleaner shrimp? and am i alowed to have another shrimp in a 14 gallon? thanks
