2 Pregnant Angelfish?

Question
I have a 75 gallon tank with a very large Pleco, a good sized fish nicknamed the snail-eater (I forget what it's called), 2 neons that have survived, 5 quarter-sized tetras, and 3 angels. Last week I had 4 angels - 2 golden pearl and 2 silver/black stripe, but I woke up one morning and one was dead. I had heard a lot of splashing and thought they were just being crazy. Yesterday we noticed the surviving golden pearl angel is very fat in the belly. Today it looks like one of the stripe angels is getting a fat belly also but not as much. I bought plastic egg-crate to separate the breeding pair but I don't know who belongs to who now. Is it possible to have two egg-laying females in one tank and be spawned by the one male? Should I just separate the pleco and snail-eater away from the breeding slate? Also I have a large Aqua-Tech filter system that hangs over the edge of the tank but I am worried about the intake tube sucking up the fry. Is it possible to cover the end of the tube with cheesecloth to protect them? The water temp is about 86 degrees and I do a 25 percent water change every other week with warm tap water and Prime. How do I perform water change without scaring the parents into eating babies?

Hi Donna,
Breeding Angels is lots of observation.  They are Cichlids, and when they couple off, the Angel will couple with just one Angel. He will never spawn two females.  The way they do this, is they grab each other by the mouth, and waltz all over the aquarium, let go, then go back, and this can go on from 15 to 30 minutes.  This is called the "Nuptial Dance".  If they are not of equal force, the stronger one, will attack, and try to kill the weaker one.  This must have happened when you heard a lot of splashing.  Which one is a pair, would be impossible for me to tell you.  You will know when they spawn again, as they will fight off any fish that dare go near their spawn.  Sometimes they are good parents, sometimes the aren't, and eat the spawn.  Sometimes, the female will look after the spawn alone, and sometimes, the male will look after the spawn alone.  To make matters worse, sometimes two females will spawn, and one female will act like a male, so you see, you must observe them carefully.  They should have their own tank if eventually you see you have a pair.  The fry must be fed Baby Brine Shrimp.  You can hatch baby brine shrimp yourself, or buy the baby brine shrimp in the frozen section of your pet store.  You pet store will tell you how to do this if you decide to hatch them yourself.  It is much cheaper in the long run to hatch your own baby brine shrimp.  The fry must be fed 4 times a day, and you must do water changes everyday, always siphoning from the bottom.  Make sure your water is always free of ammonia, and nitrites, and that your nitrates are low.  The fry must always remain in the water they were born in.   They must have baby brine shrimp for at least 10 days, then you crush dry food very fine, like salt, or powder depending on their growth, and alternate with baby brine shrimp until you have them on dry food completely.  Vary the flake food as much as you can, and when they are bigger, feed them bloodworms, daphnia, frozen brine shrimp, and a good quality flake.
Be prepared, and watch them closely.  I have spent many sleepless nights watching Angel fish.  I have had many couples.  They are always a puzzle that you must find the pieces to.  Only you can do this.
I wrap the filters arm with white nylon stockings, and have had no problems.  Run the stockings under hot water first.
I have always kept my Angels in 82 degree water.  It is my experience that 82 degrees is better for them.  The Discus fish would need 84-86 degrees, but not the Angels.
When you have good parents, or one good parent, you can do your water changes with no problems.  They will not eat their babies.  It is best to have both parents with the fry, but this depends on the Angel fish.  They usually eat their eggs before they hatch.  The parents will eat the eggs that are fungus so that it won't hurt the ones who aren't, so don't panic if you see them eating a few eggs.  It all boils down to observation, but Oh, to see a tank filled with baby angels is so beautiful to see, especially with the parents.  You may leave the parents with the fry until they are big enough to put on the market.  Feed the parents well, as this takes a lot out of them.
I hope this will help.
