Just wonder if any body could guess at what these multi-colored spots on every thing in my tank could be? I have a 40gl tank with 2 Humbug damsels, a Maroon clown and a clean up crew form here.I don't have LR, just crushed coral.But lately some spots of maroon,yellow, green,blue,and greenish-blue colors have been growing on all the shells, barnicle cluster,and Hermit crab's shells.It looks like a fungus,or mold,and I don't have a clue of what they could even be!
