They do love their zucchini! I'll have to try to float some slices. I bought some veggie clips that have magnets. Now I just attach a round of zucchini or a carrot to the clip, and guide it to the bottom with the magnet and anchor it there. Works great and now I'm not constantly fishing around with tongs to get the rinds out. Usually, there's not much left but still have to retrieve the anchor so the magnetic clip is great.
I hear you on not wanting to part with the big guy. I had a common in my 30 and traded him when he got about 4 inches because I was already attached to him and knew the longer I kept him the harder it would be to let him go.
Now I have a baby albino bristlenose. cutest little thing and grows very slowly - should only bet about 4 inches max.
