Hello everyone,
I've been journaling my 38-gallon Mineralized Substrate Tank for a while. Over the last week I've been treating the Angels and the Rummy nose tetras in the tank for Ich with Formalin and raising the tank's temperature to 84 degrees. The fish are on their recovery path and will be ending my trreatment in 4 days, start changing the water and reducing the temperature to 76.
To my surprise, yesterday I found that in the back corner of the tank, there was a small pit dug up and it was clean. That corner had a pile of organic wastes in the past. I later checked on it and found that the Rams were cleaning it. By night I found that they had laid the eggs in the pit.
I found that the eggs usually hatch in about 48 hours. Here are some of my questions, with an aim to saving the fry:

I found that the eggs usually hatch in about 48 hours. Here are some of my questions, with an aim to saving the fry:
- The tank has formalin for ich treatment and the temperature is at 84 deg. Is there a danger to the eggs? If so, what can I do to minimize the danger?
- Is there a danger to the fry from other fish and the filter intake? If so, what should I do to eliminate the danger?
- What steps do I take to take care of their feeding once they hatch?
- Should I try to remove them to a different tank? If so, what should the new tank be equipped with?
- Anything else that I should worry about?
