Pet store that treats Betta well!
The pet shop where I got Biscotti had shut down. when i got him, they were keeping him in a dirty little cup.
They reopened in a new location the other day, and I went in to get a new Betta and to my surprise, the Betta were looking much better! They were in full cups, each with a lid with holes in them. All the cups were clean. The biggest issue is almost all of them had fin rot, some were really bad too. But it made me happy to see that beside all the Betta cups there was a dropper for antibiotics to treat the fin rot. YAY! I picked one out, and the lady there mentioned the fin rot, and asked if I had a setup ready for him. After the chat, she gave me a free bottle of medicine to treat my new one. His fin rot is slight, but at least now it won't get worse.
But I'm pleased with how well that went, the lady handled it well and takes very good care of the fish. I would definitely get more Betta from her!
