I have two tropical fish and I want to find out how to tell if ones a boy and ones a girl?

Question

one i think is a boy is blue gray and purple with blue gleter spots and the one i think is a girl is yellow with yellow gletter spots

Answer 1

We will need to know what kind of fish they are first. A link to a photo of them would be great, then we can tell you what they are and if you can tell boys from girls, we can tell you which yours are.

Answer 2

Well, it would help to know what kind of tropicals we're talking about here. Since we don't, I'll have to generalize.
Livebearers are the easiest to sex. Look for the anal fin-it's the rearmost, lower fin. On females, the fin is a normal fan shape. On males, it is modified to form a tube, called the gonopodium, for transferring sperm to the females. Male livebearers are usually more colorful and smaller than females. Still, looking for the gonopodium (or lack thereof) is the only sure way to sex a livebearer.
Sexing egglayers is more problematic. It's different in practically every species. A few general rules:
Barbs and Tetras: Males are usually more colorful. Females are usually more heavily bodied. Males of some species have longer fins.
Bettas and Gouramies: Males are usually more colorful. Females are usually more heavily bodied. Who isn't familiar with the male Betta's long, flowing fins?
Cichlids: This is a very diverse group! Males of many species are larger, more colorful, and have longer fins. Some species cannot be sexed at all. There are even African species where the blue males and yellow females appear to be two different species. This may be the type you have.
Sexing fish is relatively easy with some species, and impossible with others. It all depends on what species we're talking about. Hope I've helped somewhat. Your best bet is to look for a book or web-site that shows photos of both a male and female of each species, then you'll know for sure. Good luck!

Answer 3

This question goes along with birds, usually the male birds are brighter and more color full, yea makes no sense, this may be the case with your fish. First of all find out what type of fish are they, tropical as in what kind of tropical, fresh water or sea water fish?
Once you find the specific type of fish research them at your local library. Should be able to get a good answer that way!

Answer 4

We would definitely need to see a picture to say for sure, but, with the exception of goldfish, the general rule is that if the fish is vry colorful, it is most likely a male. Females tend to be considerably duller in color. So, I would have to make a guess that, if you are seeing this much color on your fish, chances are, both are male, but again, without seeing a pictures, I could not say for certain.

Answer 5

We need to know the species of the fish that you are trying to tell the gender of.

Ask a pet store person.
