It's really good one, you can't see them often on the glass, mainly after lights off you can see them more, otherwise they stay hidden mainly.

Thanks! Looks exactly the same as ones in a Google search.

Its a 30 gallon tank that hasn't had anything added to it in 6mo. Got to love this hobby. Learn and see new things every day.
