Thinking of starting a tank with more aggressive fish than I normally keep. A few I'm thinking of would be a dwarf lion, eel ,and maybe a trigger. My questions are compatability? I've kept a trigger before and was without a clean up crew , is there something to have in place of clean up crew? Is it possible to have sps? Or is water quality gonna limit coral with these fish? If anyone has suggestions or knows of someone with a thread on a similar system would be appreciated thanks.
