A week almost ten days ago my p's laid eggs in my 300 so i moved them into a 29 gallon i alreaddy had set-up. I kept the tank at 82.5-84.0 degrees. I used an undergravel filter and an overflow filter. The eggs hatched and were doing well for 5 or say 7 days. All the sudden i woke up this morning and noticed that they are dieing like crazy. I was feeding them a combination of beefheart and daphnia. What did i do wrong. . . i suppose that i need to feed them Baby brine and keep the water changed ,. . . but how do o change the water without sucking up the fry? PLEASE HELP as i have another shot at it and want them to live.
