Sexing an axol, mud puppy's??

[deathbydisco]

i have 2 axols, one white one and one brown one. they are both about 6 inches long now and i was wondering when or if they would breed. how do you tell what sex they are? both their butts look the same to me. i thought i read somewhere that axols can reach 12 inches, tail included of corse. every one ive seen has been about 6 inches. how big do they have to be to mate? whats the difference between a mud puppy and an axol? they both have the same hair-do's. could you keep axols and mud puppys in the same tank?

you could possibly sex the axolotls at that age/size, but it'll be hard cause the probably havn't reached sexual maturity yet. they usually do this when they reach 20-25 cm (8-10 in) how old are they? i have no idea what a mudpuppy is. but i can probably help you with breeding (trying to) your axolotls. mine are breeding quite happily, i have had 5 successful lots so far.

Mud puppies are Necturus species (http://www.caudata.org/cc/species/Necturus/N_maculosus.shtml). Axies can get rather large, and can usually be sexed at around 8 inches, as stated. No, you cannot keep mud puppies and axies in the same tank. Species mixing is undesirable, and mudpuppies are usually rather agressive, and would be mean to the axies.
