yesterday my mom WANTED to go to about the reef! she usualy procrastinates on driving me down there, but she wanted to go! and she was in shock at what they were selling there! little baby sea horses. now she wants a SW tank. so this meens another tank for me yay! i told her we might not be able to set up a sea horse tank and she was fine with it. she wants to by a nanocube, i think the 6 gallon. if it had a little sun light showing into it would that be a problem? she also cleans alot(OCD) would she be able to clean around a nanocube since it is a closed of tank?
