two fat kuhlis, hanging out in the bolbitis fern.
I took it apart. Removed the rubber sleeve. Now I use the acrylic rod with wooden knob handle to nudge things in the tank, shift a leaf back into place after the current from new water being added pushes them around, or indicate a plant to someone I'm showing the tank to. I use the acrylic tube to spot-feed the kuhlis. It easily reaches the bottom of the tank. I've also found it useful to siphon small items or food debris out, especially in Perry's tank if he misses something. Or if poo is sitting on the moss ledge (which doesn't have much moss on it yet). I don't like looking at that.
Glad I kept and dismantled the thing, instead of tossing or selling it. It's turned out to be very useful as a prod, siphon straw and feeding tube!
