I am going to ambush them tonight when they are sleeping and move them to the shrimp tank. Hopefully that will be okay for them. They have now taken up residence in the seahorse feeding bowl and the seahorses are so slow and gentle I am not sure they can compete with the mollies although the mollies don't seem to bite them or anything.

I tried to catch them just now and ended up upsetting everybody. Try again tonight when regric said they're easier to catch ;)
