sometimes newt will fight it just a thing they do and not much to do to prevent it the main thing is to give them as much room as you can and keep them fed nicely but not to much lots of bushy plants like horn wort are good for them as well as it helps them hide and stay secure wen i capt mine at first i had a bear tank and used to get fighting all the time then i very hevally planted it with horn wort and elodea they seamed to carme dawn allot
newts are great fun. make sure they are not just baby paddletails as i was sold a pt as a firebelly and pts grow very big in comparison.
try not to worry about the size difference as it does happen, females are bigger and fatter. everything i read suggested that the males prefer their girls like that!
i hope it is a pair as that will (hopefully) stop them fighting. i had two male or female (wasnt sure) paddletails that fought all the time until one decided to go for a holiday down the back of the tank.
the battles are a sight to behold, and although they dont appear to damage each other it still isnt nice to see.
try planting the tank and addind 'caves' - ceramic flower pots etc, let them get their own territory.
when i first started mine were fussy eaters and the fish used to get the bloodworm first, so i used a flowerpot, placed against the glass that only the newts could get into and put the b/w in that. once they found it, they scoffed it and they've never looked back.
i keep mine with african clawed frogs now and they are very happy.
ive got my 2 in a 15-litre fish tank with about 1/3 full of water with gravel substrate in the bottom, unheated with a Interpet PF mini for filtration, i dont keep them in with my fish as i tried it before but the newts hardly ever went in the water and the fish did occasionally nibble the newt if it was in the water
Both newts are feeding well and occasionally when i go over to feed them or look at them, they are on the top of the castle ornament mounting each other (snuggling, perhaps?)
i will probably try filling the tank up to about 2/3 or 3/4 full and see if they are more willing to swim
the tank isnt very well planted, one small artificial plant and 3 large twigs, a piece of floating bark and a large castle ornament
ye they ar cute i had about 6 at one point mine did spend quite a while out of water but they do tend to feed in it its best to give them a land mass and plenty of plants and reading that article they can live for anything from 1 to 60 years (waw) have a read of this
They seem to do well at temperatures ranging from 60 to 70 degrees Fahrenheit. It has been reported that they will survive lower temperatures of 40 degrees, but this is not advised. If temperatures are too high, or they are overcrowded, Fire Belly Newts may experience appetite loss
