I have six discus in 35 gal tank that is connected to two other tanks(total 75 gal).Can I expect solid growth on my juvies( fed four times a day) due to relative shortage of space?
Here is my take on it...if you put 4 discus in a 10 gallon tank thats connected to a 100 gallon sump making the water capacity 110, would the fish grow to full size? No, I don't think they would because they don't have the physical capacity to grow. Now that is just my thought. Use the 75 to grow the 6 discus out. Wouldn't that be easier...
Agree with Eddie, Water changes my friends and lots of them!. Thats going to be the only way you every get your fish to be what you want. Im sure the 35 would be ok for a little while but once they get bigger 2.5 or so its probably time to move them to a bb75. Good luck and take care.
