Hey guys, so i recently bought a pair of juvanile channa marulius and have them in a 150 gallon tank. Its been about 4 months and one of them is growing really fast and seems to be very comfortable in his home. The other (i am assuming the female) isnt eating as much as the big guy and is growing much slower. Bought them as a breeding pair but i am worried that the big one is almost big enough to swallow the small one now. What should i do?
