You don't need to worry about the bioload they put off, because they don't really create waste. But what you do need to worry about is the chemical warfare aspect. LPS
, just like many corals, put off chemical defenses to protect them from other corals. LPS
usually have sweepers too, so they need to be spaced atleast* 5-6 inches apart. I have 4 LPS
corals in my 29 gallon with no problems.
