This is my 100 gal tank that I have redone. I redid the rocks and caves, and I lowered the temp in the tank to 78-80 degrees, and my yellow labs have bred for the first time in about 8 month. I wonder if it has to do with the temp change? My heater went nuts and the temp was way high. I finally got the temp. under control. Now my yellow tailed acei male is showing his breeding colors, and is after the female. I bought some more peacocks, too. Maybe eventually get some peacock babies? Hope so!
