Small white bugs crawling in tanks

[NatureLady]

Sorry for your loss.

Google mites and springtails. Mites are bad news, but usually black. Springtails are janitor bugs and would not have been the reason for death. If your skink threw up, she almost drowned.

Do you have anything in the tanks that could have had springtails?

black and red mites are the ones you need to watch out for. white mites usually decompose organic matter in the tank but I would examine them and ID them properly. you may need to get some sort of magnified glass to see them. mites are extremely tiny
