not so sure about the discus as I have never kept them, .....
but angel fish and gouramis are great at keeping the guppy population in wont see fry at all unless you have great hiding spots

Hi there: Angelfish will quickly put a big dent in the population of your guppies. The adult guppies are too big for the angelfish so they will not even bother with them. Sounds like you have more than enough room in your fish tank to accomadate angelfish or have you maybe considered getting a few more discus to control this problem????? What are you feeding your discus that they are not eating the baby guppies???? At one time my husband and I had discus and we had swordfish in with them and it didn't matter how many baby fry were in the tank with them because they would eat them as fast as the swordfish had them. We had five discus in the tank with six swordfish and if you can imagine just one swordfish can have up to two hundred fry. That's alot of live food but not one baby ever survived the five discus. This is way I'm asking you what else are you feeding your discus??????

i feed my discus bloodworms, brine shrimp and just your typical flakes, they never seem to even take an interest in the guppies really.... that is the whole reason why i got the guppies so my discus could have all the live food they want

I have a F and M Black Convict, they spawn and raise fry regularly. In the last batch I see a pink colour fry, now .5" long. Anyone know about this. I have read about pink convicts but thought they were from 'Pink' parents, ie a species of their own.

The F and M Black Convict I have are very strongly coloured, black vertical stripes, the F has vivid orange scales along underbelly and base of dorsal.

A school of larger tetras like black skirt tetras would love hunting down all the guppy fry.

Xandra, this probably should have been a new topic, but to answer your question, pink convicts are not another species but a genetic variation. Your black convicts may carry the gene. It is surprising you only have one pink one out of all the fry you've had, so it is probably a mutation (or some of your fry matured carrying the gene from one parent that was for the pink color and bred with each other). With recessive traits (and I'm not sure if pink convicts are recessive or not, you'd expect to see 1/4 of offspring expressing it if neither parent does.
