I picked up 8 of these guys several months ago at pet smart for $0.99! They have been very nice active schoolers. However 2 of them now have developed tumors on their heads. The first on got so big he couldn't eat anymore. Fish seemed otherwise completely healthy, perhaps that is why they were only $0.99 :/
Thats a good deal, my local fish shops sell them for $2.49 a peace! Fish arn't cheap in my town
