We started off with the package coming late in the day I quickly opened it up and had 2 on there sides . They were absolutely freezing the heat packs were still warm though. One of the two has bounced back but a couple are so skinny their skulls are sunk in on the sides I placed the skinniest one that was on its side in a breeder box with some food close by. He is very very lethargic to the point he doesn’t seem interested in food. I don’t think he will make it. The other seemed to bounce back a bit in the warmer water although it is also very skinny with his fins being beaten up. The rest seem to be doing well and are very pretty little fish. It’s a small rough patch but I think I’ll still have a beautiful school of black Venezuelan cories. I would still recommend angel fins but I thought I needed to be honest to help better your business in the end.
