When I lived on the farm I was raising Angel fish and had few problems with hatching the eggs. After I had moved to Melfort I set-up my tanks again, bought some young stock ,
put them in a 70 gallon tank to grow out and pair up. When the pairs showed themselves I moved them to 20 gallon tall tanks in the basement tank stand and set them up for breeding.
I fed them well and very soon they were spawning but I was unable to get them to hatch. I tried them with the parents because I wanted the parents to raise them and after failing that I tried to hatch them artificially-if my memory serves me correctly I had two fry hatch and survive. Well to make a long story short I got frustrated, sold off the stock . Its been awhile and I can't remember all the details of anti-fungal medications I used on the eggs etc. but if any of you have gone through this and have solved your problems I would enjoy hearing your experiences. Thanks
