So today while at petsmart I of course went to look at the bettas. Didn't plan on buying any until I saw this tiny little veiltail [I think, his tail is really tiny and not fully developed] dragon scale boy that was no long than an inch. All of the bettas were in pretty good condition but he was emaciated. He also had stress bars. I couldn't leave without him. I brought him over to someone and pointed out how skinny and under developed he was and they said the recently got a shipment of really tiny bettas, and for some reason they aren't gaining weight. I'm assuming he's just too tiny to eat any pellets they're giving him. There was one other tiny HM dragon scale that looked to have maybe fin rot and was also skinny, but not quite as skinny. It also seemed like he couldn't swim down. I really wanted to take home both of them but I couldn't afford two today.
Right now he's in a smaller holding tank while he recovers, and until I can get my new 10 gal. cycled. Do you guys have any suggestions on helping him gain weight? I was going to give small frozen bloodworms, but I want to make sure that's the right thing to give.
Thanks for any help!
