Tried to add a new powerhead last night

I tried adding an AC 5000 power head to my 125 pygo tank, I had to remove it because they all started fighting worse than I have ever seen. I am going to try again this weekend when I have more time to monitor them, and rearrange the tank a little to take out any territories. I was just totally caught off guard, it was mainly my larger yellow natt that got his territory invaded by the others and then he started cleaning house. They were ok for about 5 minutes and all of the sudden it was just a mad house until I decided I needed to shut it off. As soon as I took it out things calmed down again. I am thinking about running some PVC pipe under the gravel to create a river effect tank, that should work off some of the aggression of the bastards.

You seem to have a good grasp of what they like as far a gph in a tank and now you are telling me that 900 is too much when
I think it differs from situation to situation. Mt tank is 52" in length, and I only use a 325gph powerhead, but my reds don't like it one bit. They basically just ignore it.

I think all you can do is make recommendations (and I think that was what Nate did, although he could have stated it more strongly) about the gph-to-tanksize ratio, based on your own experiences. I believe any experienced piranha owner (and I view you as an experienced piranha keeper, Jeff) should know that information from hobby sites like Nate's or my own shoud be seen as based on personal experience, because we simply lack the tools and skills to make and back up scientific statements. Info you find on sites like that should be read/accepted with precaution, imo, but it should also be stated on the website itself.

Just my 2 cents.... :smile:
