Well, my angelfish laid eggs on the intake tube of my filter, so I let them watch the eggs for two days... I was planning on taking them out when they became wigglers, but mom started getting hungry and ate 80% of the eggs, just as the tails emerged... I yanked the tube when I got home and put it in a cycled bare bottom 10 gallon tank at 84 degrees. That night they started wiggling! The problem is, most of them fell off the intake tube and ended up on the tank bottom.... along with crud from the tube. I vacuumed the bottom, so it looks clean, but the wigglers got stuck in some of the crud. My question is, will they make it even if the are piled together in a heap that contains this crud? What should I do?
