OK well he is the biggest, he is the first one out to the food. I am feeding wafers at night and large fresh zuccini in the day. He eats so much but doesnt gain or grow. He has plenty of hiding spaces, more than enough. Not getting harrased, his fesces is the same as the other plecos. He is in a 250 g. with a puffer that has learned to respect other fish in the tnak, a TSN, black ghost,and a spotted gar. Amonia-0 Nitrite-0 Nitrate- between 5 and 10 ppm, after 10 ppm I get weird and do a 30 % water change. He is living the life but not getting very big and very thin. Not scary thin but just huh... thin. The other rasp the huge driftwood but he doesnt. He even shares a piece of zuccini with another pleco with no problems. He is way too big for any others in the tank to swallow.
