EBR January 30, 2008 Share January 30, 2008 The drain is an up-turned elbow in the right back corner of the tank, and my sleeper goby has a really annoying habit getting too close and riding the drain to the sump. Any recommendation on how to prevent him from reaching the point of no return? I've already got a piece of egg crate grid in the elbow (1.5" dia), but those 1/2" holes are apparently too big to block the little squirt. Thanks.
