Hey guys, other than turbos, im looking for other inverts and a fish too if possible that love eating diatoms and other micro algaes if any. Do urchins eat algae too? Will they eat diatoms? Also im planning to add a lawnmower blenny, will it nip my gsp? Coz iv heard from many that blennies nip at lps, gsp and clams etc. Especially bicolour. So dont want such fiah in my tank. The hermits we get here are not at all reef safe, nor we get emerald crabs here.
