You cannot provide it in a 5g.#ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl#They do not suggest even getting one unless you have a 35g or larger. They suggest no more than 1 per 65g & even when it's a larger tank they suggest only a male and female set.#ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl##ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl#I have both kind and they live happily on opposites sides of the tank. But they do not seem to be aggressive toward each other at all.#ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl##ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl#I would like to add a female but I am scared to just add her for no good reasons. Instead I will just replace some of my cleaning crew someone is having a blast taking from their shells and then spitting them out some what chewed!#ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl##ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl#DO some solo net research or look up the specific fish you are asking about here in the forum. Maroon can get quite big and I would think would not be happy in that small of an environment.#ed_op#/DIV#ed_cl#
