Who has a Betta?

Many cities and towns use chlorine and ammonia to kill bacteria in the pipes that carry water to the tap. You must be on or near the end of the line so that there is not much chlorine left in the line when it gets to your tap at work. I would still use a chemical that will neutralize the chlorine and also to make the metals less ha4mfull to the fish. I have 10 aquariums running and I make sure to add the chemical that will neutralize ammonia, chlorine (chloramine) and heavy metals. I do not wish 6to kill any of my fish. I have some of them breeding for me and I will be setting up a fish room for up to 100 aquariums just for breeding and raising tropical fishes.

I don't know about you but I was always told that chlorine is bad for fish. I have a 10 gallon aquarium and when I do the water change I either use the start right liquid or the tablets that make it safe for the fish. Chlorine causes stress on a fish's body. The start right liquid or fizz tablets by Jungle helps to coat a fish's body and keep it from getting stressed out. I have a betta and it is in my aquarium with 2 other fish right now and I have no problems with mine. I do think that this behavior that you are describing is from the tap water. I find that my betta loves my water filter in the tank. He will sit under it and let the water push him down then he will swim right back up and let it do it again. I hope that this helps. P.S. THe tablets and liquid I told you about only cost about $4 at wal-mart.
