A bug tank??? a refugium used to supply the display with bugs (zooplankton). Here's a pic from last month. I've now got the typical "new refugium" syndrome. some hair and some Cyano. But the bug populations are incredible. You should see how fat my Mandarin pair are 8O
he has been in my tank for at least a year, with no predatory action. I'm not sure what he eats but I defenitely do not target feed him. He is in a 30 gallon with a serpent star and a blue linckia.
