Keeping a wild caught salamander

Hi, I have been reading all day and searching for relevent info on a pair(actually 4) salamanders I found. I let 2 go, but I want to keep the big one and one of the small ones. They are long toe salamanders I think. I found them in a really small pond. I read the care sheets on them and it says they need to be kept in a tarririum, but they were in the pond, under the water. I thought that they were lervae, but they have no gills and one is much to big to be that young, about 4 inches.

I guess what I am wondering is this- should I keep them or should I put them back in the pond? I have kept tigers for years and I would like to keep them, but not if this particular species does not do well in captivity. Any help would be great. Also, I find it strange that they would be in the water, i was told before and I read a few posts that state that salamanders will drown in water, yet these were almost walking in the shallow part of the pond. Has anyone seen that before?

see if that helps

ive red that its fine to keep them but sometimes they carry infections if they are wild and that you need to now what there proper spieces are to feed them and all that!

I think there is a good chance that their preference for water versus land depends on temperature. Once you bring them indoors, they will probably stop staying in water. Your best bet would be to give them a setup where they can choose water versus land and see what they do. If you do keep them, it would be bad to release them later, as they can pick up germs in captivity and then take them back to infect wild sals, so be sure you are committed to keeping them.
