Where are you getting the fish from ? I really do not want a fish from a pet store. The fish are in a small plastic container for months until they are purchased.
The aquatics store my housemate works in keeps them in proper tanks thankfully. Just waiting for them to get in their next shipment. Half moons and crown tails only come in very rarely and they only ever order a small number of Bettas at one time. Luckily I get to put a hold on any fish that come in that I'd like and I work really near by the store. Also, my housemate manages the fish house, so he can tell me if the fish arrived from a reputable breeder and in good healthy condition.
I know that Carole @
waterfaller1 has ordered/won them straight from the source. If you have no reputable stores or breeders near you, that might be a good option.
