I’m currently stocking my JBJ 45 and am shooting for having a very low bioload so that my tank will hopefully be able to go 2 maybe 3 weeks without a water change if the wife and I go on vacation (I really only trust our pet sitter topping off the ato and feeding). It’s a reef tank and has two premium Picasso clowns right now. What can I add that would also result in a low bioload overall? I didn’t know this but cleaner/fire shrimp count as a small fish? In the end to make it work, I’m fine keeping just the clowns and getting a shrimp but would like to get a flame angel or another dwarf angel and maybe a watchman or diamond goby but worried about the bioload then. Thoughts?
