I personally would not try to keep 2 pachy's in a 10 gallon. When I first got paddletails some years ago, they were given to me unexpectadley by a friend. I had 4 in a 20g for a little bit of time before I could get another tank and they all got along for only about a week. I feel they are too terretorial to keep in such small confines. I have 2 paddletails in seperate tanks right now and as soon as the newer of the two is bigger, I plan to introduce them into the same large tank. This tank is 4 ft long and I plan to have a ton of hiding spaces available for both animals to feel secure. I also am going to hand feed to try to lessen aggression over food. But I am still going to have a tank ready in case they just don't get along and I have to seperate them. Since you have had difficulty getting a good tank for your single animal, I wouldn't recommend getting a second paddetail at this time. If you really would like to get more newts, read and learn as much as you can from this forum and acquire some CB animals. Make sure you have all the neccessary equipment before hand as well.
