Hi, thanks...I put some taller plants in the front is so they can actually have place to hide... I have two very curious cats who will sit there all day with their noses pushed against the glass and the fish were looking a little nervous. After the cats get bored with it, I'll probably rearrange the plants. We're talking about two cats that scooped a betta out of a bowl and also scooped my snail out and was playing with it on the floor! There is a cover on the tank but they have already figured out how to take the cover off the filter...not sure why... but I had to tape the cover on my filter to keep it on there... talk about delinquent cats!! LOL
