Thanks for the advice, aside from the water issues if the newt will eat anything that it comes across I'm sure my eel will not like such an idea and turn on him within a few seconds. The only other tank I have has baby sword tails so I'm going to assume by what you said that they would not do well with him around them.

So, does anyone have an idea then as to the size of tank a newt like that will be happy in? I have a 20 gallon long at the house, should that be big enough for him or would something a little bigger be better?
