Well from what I have read, some people suggest changing half the water in the tank with clean water, while others say to leave the same water for two weeks so the fry can also eat off of the natural stuff that will grow in the tank
i would leave the water the way it is and just take out the big stuff, and then slowly add water that is the same ph and temp as the water in the breeding tank, like just drip it in, and fill it over about a week or two weeks
Alright everyone thanks so much for the help. I will continue to refine my methods until I have found a suitable course of action and of course continue to read up on Bettas!
