Yeah all the pet store owners around here give me weird looks when I tell them I have single Betta's in 4.5 gallon tanks. Theres only one lady in one store that realizes they should be treated like any other fish with their housing & she is always shocked by how much I've been telling her about them [which I pretty much all learnt from this site lol].
I want to work at our big pet store here, because they like to hire people who are trained in particular areas, & I know they don't have a Betta expert, but 1. I really dont think they'd appreciate me telling all the customers that NO, you CANT keep them in a half gallon tank & expect it to be happy/survive & 2. Im trying to get a promotion at my current work & getting a second job wont help that situation lol. :(
