From what we've researched, we have set a separate smaller tank with water from the same tank where parents are from. Before placing in the tank, we dipped in an anti-fungal solution known as Methylne Blue for a few seconds then placed them in a breeder tank with a diffuser under them to slightly tumble the eggs.
Some are hatching and the remaining have turned white in color, which I assume is infertile eggs (please correct me if I am wrong). A few fry that have hatched have died and the remaining are still switching around with their yolk sacs on the bottom of the tank.
We were told not to have a circulation/filtration pump due to the risk of having them sucked up, even if we covered the suction tube with fine nylon mesh. We were told to place some barley which is a natural way to keep the water clean, however, my concern is the dead fry and unhatched eggs may ultimately make the water toxic and without a pump and filter, how would we clean and maintain water quality to assure fry survive
Also, I was told not to use a flash light to inspect the tank or turn on the lamp to the hood. Is this rumor or true and if it is true, how would I visually inspect fry and clean the tank from the dead and unhatched eggs
Any guidance would be appreciated!!!
Thanks!
