My wife is a fifth grade teacher and she has told her students about my tanks, now they are begging me for a tank with a star fish in the classroom. I have a 10, 20 and 29 gallon I could use for this but haven't decided which one yet but when I do I may need some help from some of you guys on locating some livestock, I have most of the hardware for now I'm trying to keep the cost down as much as possible. This tank is going to remain in this classroom except for when school is out some of these children have never seen the ocean so I'm going to bring as much as I can to them. I'm not begging for a handout but Imay nned some help in the near future locating some livestock reasonable.
