Ruth will probably have my head if I didn't mention that we had Ralphie (her betta) over while she was away back home. JoDee and I have never seen such a spoiled fish. Of course we naturally took his bowl and put it over by Marty (our betta) just to see what would happen. Needless to say, Ralphie erupted in a flurry of male-rage that betta's are famous for. Marty swam around for a while. We're not sure if he can see through the plexiglass well.
