Re: clown triggers clown triggers can get up to 14-20 inches long the wild. i don't know if they would get that big captive. i haven't heard of anyone having a trigger that big. eventually your tank size depends on how big your trigger gets, how many fish you have and how big those fish get. in general triggers that get 6-8 inches long should be kept in at least 100-150 gallon tank. |
