I am sorry for being a newbie but i have to ask.
I just bought a 10Gallon Tank w/ Filter
two bettas w/ plastic plants
at first one of the betta had a very nice tail as hours goes by the betta tail looks like its kind of ripped. but the thing is that they only fought once or twice and they really dont pick at each other tail or i can be wrong. they first where swimming around but then couple hours later one of the betta decided to lay near the ground for the rest of the night, while the other was swimming and eventually slept on the plant ( the betta that was swimming around didnt really go to the betta that was resting on the ground). When i woke up both betta was in the same position.
After i realize the bettas didnt move, i decided to look around and see what might be wrong, I eventually bought a HEATER for the tank and would assume that the water was just too cold. as i put in the heater the betta that was on the ground started to move more and moved near the heater.
the question is If the betta tail is damage ( by bitten or something else) will it go back to normal? or is it forever damage.
