It is 28g and my ammonia and nitrites are 0. My nitrate continues to be in the 20-30 ppm range, I can't seem to get them to 0 and I have been doing 10 to 25% water changes 3 or 4 times a week. My tank is medium planted.
EDIT-My tank has been up for about 7 weeks. I started with the fishless cycle and did the 90% water change before I added any fish.
EDIT 2-Also, one of the gourami's has been acting really aggressive he seems to be trying to build his bubble nest even though there are no females in the tank. He chases the other two gourami away whenever they get close. I still am not sure can rule out an attack on the tetras from him? I mean the one was basically missing its head and tail section. And the other was missing its eyes couldn't tell if it had any other bites. Would those diseases completely make the one corpse look like that? headless and tailless?
