I take my eggs out and sometimes wigglers to my 10 gallon tank. What might have happened was it was not cycled properly or they died from water temp shock. with fry BUMP THE TEMP SLOWLY to 84 degrees speeds up metabolism so you can feed them 4-5 times a day and daily water changes. Since its a small tank like mine the water paramaters can change fast so I do 10-20 percent daily and feed them twice a day because I am not home. On the weekends I feed sometimes 5-6 times a day with water changes.
Its common practice to leave with parents but I breed and many batches so I take them out. You have a higher survival rate without parents because overnight they can eat them all or a few to get ready to spawn again.
