how can you tell what sex tropical fish are?

Answer 1

Male livebearing fish have elongated anal fins. It can be very hard to tell (or impossible until spawning) with all others. Some fish are even capable of changing sexes if they are all of the same sex. You will have to search the info according to what fish you are talking about.

Depends on what species, some you can tell the differnce by size shape or colour some you cant.

There's no quick answer to this question. There are hundreds of species that are commonly available and sexual identification varies according to species or groups of species. A more useful way of posing the question would be "How can you tell what sex Swordtails are?" or "How can you tell what sex Zebra Danios are". james
