Fish Crazy
i want to get a dwarf gourami male for my 20 gallon, would a female pearl gourami or honey or kissing mate with it. would the male be aggressive towards them.

some reasons that cross-breeding is not recommended:
-- any instance of hybridization is a lost opportunity to breed pure-line fish and reduce the number of wild-caughts on the market (this is a huge factor of the population depletion of several Rift Lake Cichlid species and Endler's Livebearer.)
-- hybrids resulting from closely related species (such as dwarf and honey gourami) could easily resemble closely the parent fish and be sold as such. should these be somehow bred back into the parent fish, desirable characteristics such as small adult size or coloration would be impaired while undesirable characteristics such as infertility could be introduced to the line.
-- often hybrids do not carry full expression of genes carried by either parent species, being neither one thing nor the other. this situation applies to such crosses as platy & swordtail; a male platyxswordtail is likely to have a blunted or only partially formed sword. platies are prized for the roundness of their fins, while swordtails are prized for their long and highly defined swordtail. the hybrid exhibits neither of these qualities; its children (should a female unwittingly be bred back into either species) would be similarly lacking.
-- hybrid cichlids often display the worst possible combination of temperments resulting from the parent species. thus blood parrots can still be absolute terrors even with their tiny mouths and flowerhorns essentially must be kept in "solitary confinement".
-- new or simply less-popular types of hybrids are almost completely unpredictable, making it difficult to house them properly in the right size tank with compatible species. this is the reason that most serious aquarists refuse to purchase "Mixed African Cichlids" for their Rift Lake tanks. they've put in too much time and money to risk it by adding a rabid wolf that looks like a sheep. similarly, most serious aquarists who own easily interbred species such as the Rift Lake cichlids will not keep closely related species in a tank and euthanize questionable spawns. there really is no way to responsibly dispose of hybrid Rift Lake fry.
-- responsible disposal of hybrid fry is often quite challenging. to responsibly dispose of hybrid fry, one needs to be certain that the fry are clearly presented as hybrids (not a parent species) and that any fry resulting from the first batch are also clearly presented as hybrids. that means that just dropping off a bag of platy-swordtails at the local LFS is out of the question. the most complicated factor of disposal is finding another person capable of responsibly disposing of fry that can also find yet another person capable of responsibly disposing of fry. a significant portion of serious aquarist are simply Not Interested in hybrid fish. the un-serious aquarist often cannot be trusted to take disposal of fry seriously. if breeding fertile hybrids, one is presented with quite the quandry!
