Ok all. I have a cleaner shrimp in a 20 gallon. I had a yellow coris wrasse in there with him but he jumped the day before yesterday. I am not going to put any new fish in the tank and the wrasse was the only one in there. SO my question is will the shrimp be ok with no fish? And do I need to feed him, or will he be ok without me feeding something. Please advise on this b/c I dont want the lil guy to starve. I have another tank I can put him in but figured i would leave him be to have some movement in the tank. Thanks is advance.
