I have seen that tank gets horrible review for leaking and stuff. I love glofish and do have a 20g freshwater tank in my house. I was considering getting this for my desk at work but decided against it based on reviews.
If it's for a kid in the grouphome why not get him a betta?
There's all kinds of cool tiny tanks and the kids are more into fish than corals. IMO anyway.
+1 Erin...plus does he know anything about taking care of saltwater? If he's a grouphome, do you plan on supplying him with his water for changes? Betta is the way to go, IMO too.
