i was searching around here, then i got an idea to see if petco had some halfmoons. luckily, there were! so, does anybody ACTUALLY know if they are halfmoons? petsmart only has veil tail and crowntail. so lame.
i'll get my supplies at petsmart, then get the fish at petco.
I bought a HM from Petco. I used a mirror to get him to flare and his tail is indeed a full 180 degrees when fully fanned out. But his fins just aren't as ruffly or large as those of my HM from a breeder in Thailand. They almost look like two different types of bettas.
The Petco HM is very cute but not impressive-looking like the ones on Aquabid.
Not all of the HMs are HMs and not all of the deltas are deltas. All of my guys are from Petco, and some of my HMs were labeled deltas, and some of my deltas were labeled HMs. If a fish is OBVIOUSLY a delta (like, 130 degrees or less) it would be worth pointing out to the manager and see if they would give it to you for the delta price (if it is labeled as a HM). However, I have found that it usually goes the other way - more deltas are actually HMs. And I finally realized why. I now work at Petco and when I was putting our shipments of bettas into cups the other day, i realized that they are broken down into deltas and super-deltas from the sellers, but put into delta cups. And because these guys are young, many of the super deltas can/will turn into HMs.
