When so many species of fish are extinct or near extinct in the wild, we are doing them no favours by breeding hybrids....what is worse, hybrids often are not obviously so, so it is easy to accidentally pollute a pure line if you are not careful. In the case of some hybrids, the result is a deformed fish...hardly a favour to the fish, non?

Yeah I guess.. My swordtail male is actually a platy and swordtail hybrid.. He has a deformed side... But i mean, cant breeding hybrids create different fish.. or even larger or smaller fish? -- im not well education on genetics or anything but still..

Yep, and it's been done already, quite a few times. Many sunfish, trout, bass are hybrid. Alot though..are deformed, don't live as long, and are sterile.

I have seven hybrids and absolutely love them. They have been through ich (the only survivors), the stress of cycling twice, and the most recent mysterious fish deaths. I don't see anything wrong with it, as long as it is controlled. People always say that there are so many other beautiful fish to choose from, but where I am from, it is impossible to get any of the other cichlids. It's a hit or miss with the "Misc African Cichlid" and ordering gets me nowhere. I put in an order for a couple cichlids about 10 months ago and still have not received them.

There is a difference between crossing two different species and crossing two different strains of the same species. Both get called hybrid.

Crossing two different species results in "mules" sterile and sometimes deformed. This is a true hybrid.

Also, hybrid might refer to crossing two different strains, depending on context. This means fry will be fertile and deformities are not due to mixed up genetics (different numbers of chromosomes etc.). With Africans you can have Labeotropheus trewavasae of different colour morphs crossed. African mbuna entusiasts hate them being crossed because each colour morph comes from a different part of lake Malawi. Then you get all sorts of colour varieties in the fry and a real mixed bag when those fry are bred.

Have a look at the link and notice the distinct colour differences between the males of each location. When genes are mixed the original colour pattern is lost and very hard to recover (if at all).

I persoanlly think apart from BloodParrots hybrids arent very good for the fish or to have. My opinion is short and sweet. LOL

I saw some parrots labeled as Blood Parrots at a petsmart and they were orangish with some spots of brown. Didn't seem normal to me, are they most likely painted?

No, they aren't painted. Depending on where the brown was, it either means stress or it's just from breeding. I have personally never seen a parrot with the brown from breeding, but I have seen pics online. They are not painted if they are orange/red or yellow.
