looking for fish that will help eat sponge

[nrosdal]

i have sponge popping up everywhere in little white spikes that turn dark in color and also coating the undersides of caves and ledges with thick layer of yellowish almost fluffy lookin sponge.

it is not a big deal for the most part, but it is coming up alot and the yellow stuff is bugging my colt if the current takes him into it.

looking for something like a dwarf angel that is likely to nibble on sponge and hopefully not my lps.



you can see a bit of the yellow stuff here
