| ok, tried shaking out some macro in the main tank and sure enough quite a few of the little critters fell off. The Blennie is amazingly good at finding them though. For being something that easy to eat, they sure don't hide very well. Guess they make up for it in numbers. After a very short while if there are any more in there, the Blennie sees them long before I do.
Thanks for the help |
