Anyone got any ideas for how to lure a large (very large!) brittle star out of hiding, without moving the rocks out of the tank? It's a 29g NanoCube.
Fortunately, if I have to move the rocks, it's a stack of only two; and the smaller one can remain in place. It's not like I don't have the means; I've got two 5g buckets, after all...I just don't want to risk not being able to regain the current balance (physical and aesthetic).
I've tried baiting him with raw shrimp and raw scallop but the best I get is three arms, and the other tank denizens make their presence known as well.
Might he just let go if he notices the water draining from the rock as I transfer it between tank and bucket? Or is there some process of getting him to give up his home and dive into a bucket full of "fresher" water?
Hmmm...that just prompted an idea: suspend his hiding-place above a couple of inches of fresher water, with about ¼" - ½" submerged, for maybe 10-15 minutes (or longer?) while maintaining wet surfaces for the other organisms with a spray bottle...
I could try this during next weekend's WC
Might even get rid of the largest bristle worms from the rocks at the same time; and/or collect a few of the small brittle stars as well...
Comments & suggestions...?
