8 or 10 more???? At $10-15 each, I won't be in hurry to get that many at once. (see how I say "at once")

Anyway, I definately wouldn't consider getting any while Bonkers isn't eating. I'd wait quite a while. Though with now having my 20gal. tank sitting empty, it would make a great quarantine home.
I re-did the land area of the tank, and have included a pic. No more open areas of gravel to maybe accidentally swallow. I sanded smooth the opening of the upside down pot, so don't fear, there's no sharp edges anywhere. And besides that hidey spot, they can easily get behind it and the hanging plant to an area that's quite private for them.
