Yes. its coated with an epoxy resin and it really isn't taking up as much room as it looks like. he's got lots of room in front of the shell. he also likes to rest on it. I've kept bettas for years and I know just how to keep them happy. people should stop worrying about how much room they give a betta, as long as they're not keeping it in a container so small that their waste would accumulate quickly and effect their health.Are you sure the shell is coated with something fish safe? I'm not trying to give you a hard time but it takes up a lot of room in his tank. Also just a suggestion...I'd make sure he has something to rest on. I've owned some big finned DT's and their fins tend to drag them down. I'd hate to see those pretty fins munched on.
