Thank you very much for the info.. Sorry for the bad pic, but it was taken about 15 years ago at my old house (hence the old-school looking TV - lol). The newts were definitely purchased at Petland Discounts, Inc. Besides Western newts, also in the tank above were Eastern newts (Notophthalmus viridescens, yes Jennifer M.) as you can see the one toward the back, right; African-clawed underwater frogs (Xenopus laevis) like the one toward the back, to the left of the heater; and red swordtail fish (Xiphorphorus helleri) as seen toward the back between the 2) fake plants. I had no idea what I was doing at age 15, as I currently would never house all of those different species together.
I'm setting up a new 30 gallon tank, and have just ordered some Japanese Fire-belly (Cynops Pyrrhogaster) young, adult newts. Joan S., I would def. be interested in purchasing a few of your Western newts if they would be around the same size as the Japanese ones I am getting (so they won't eat each other). I've seen the 2) different newts housed together in plenty of fish tanks at pet stores while I was a kid, so hopefully they will get along with each other in my tank, as well. Thanks again for all of your help.
