Hello everyone I have been captivating daphina for about 2 months now. I took out what was left in my culture so I can put them in a 5 gallon bucket and restart my 50 gallon bucket. When taking out my last hundred daphina I noticed these little black dots that would swim it crazy speed. I put them all in a white bucket and noticed 1000s of there's little dots. I want to know what you all think they are BC I have been feeding the daphina to baby axoltlos and i just got a new batch of axoltlos eggs and I don't want these blackthings in the water if there bad
