In my experience, it is not typical to be getting both nitrites and nitrates within one week, but I don't think it is cause for concern. As long as nitrites and ammonia eventually go to zero, everything will be fine. However, as noted in the fishless cycling guide you linked to: I will offer...

84 degrees seems too hot for most fish. Also, the water temperature should be held stable, as I believe even a fluctuation of one degree puts stress on fish. I would only try to change the water temperature that much by adding hotter or colder water in an emergency, as the temperature change...

Thanks for the information. I'm surprised that tetras can tolerate that amount of salt, but I guess you can tell by their behavior how well they are. I will know in the future that it may be possible to put salt in with my tetras. Fortunately my water quality appears to be good enough that the...

Interesting... This is exactly the kind of data about salt and tetras that I was hoping to find. Could you tell me what kind of tetras they are and how much salt there is and how big a tank it is?

Thanks for responding. I have been planning to get more bloodfin tetras. (I would definitely already have them if I didn't have a patient in my quarantine tank.) I was thinking about the possibility of adding aquarium salt to the tank. It does seem like a good idea for some fish that can adjust...

I have a 20 gallon tank with two bloodfin tetras and two male pygmy gouramis. After a little fighting when I first got them, my two pygmy gouramis have lived together peacefully for three months, frequently appearing together. Yesterday one started pursuing the other around the tank. I tried to...

Thanks. I wound up quarantining him a few days ago. He's on salt and Maracyn 2. The Maracyn 2 is just kicking in. I think what I discovered is that while the water in my main tanks tests well on the usual parameters (hardnesses, pH, nitrites, nitrates), the problem was that my gravel was not...

Yes, looking closely I see that the edge does look ragged. I guess this points to fin rot. These fish were shipped cross-country, and then an experienced fishkeeper put them up in a bucket for a week. The water quality and food quality were good, but I think the lack of hiding places might have...

Saturday afternoon I added three pygmy gouramis to my 20 gallon tank (previously occupied by two bloodfin tetras for a couple of months). They seemed to acclimate with ease and settle in fine, and they were far less shy than I had been led to expect. Sunday evening I noticed that one fish...

This page, Algae Competes with Plants, says a little about competition between types of algae. Marimo is a green algae so it will out-compete other types under the right conditions (enough nitrogen and phosphorus in the water, and high light conditions). I believe that marimo and plants will...

I currently have just two bloodfin tetras. TetraMin flakes will float on the surface of the water until the fish get to them, and then debris will start to sink. Since I only have the two fish, they don't always get all the crumbs before they hit the gravel. It might be easier to keep the tank...
