I'm cycling a 135G tank, it's been a week with no progress. 1.0ppm Ammonia, 0 nitrite, 5ppm nitrate, used Tetra SafeStart. pH 7.8. I can't stand these little orange comets anymore, so I want to add some fish. Hardy, and common. I'm really think that the cycling is gonna be really long, slow, and uneventful at this point and I can get away with some slow stocking now before the cycle finishes. Would Pictus catfish be a good candidate for this?
