Hi all. Haven't been on in a day or two. Thanks for all the info. It's been very helpful. I found out a little while ago that I was overstocked. I had no idea that Comets needed 20 gallons each. I'm saving up for a bigger tank as we speak. I've ordered a secondary filter to help out for now. It will double my filtration and I've got a second air pump on order too so I will have plenty of dissolved oxy for my little fellas.

I even gave up smoking yesterday so I can save up for my new tank even quicker but its gonna cost a fortune because not only do I have to get it delivered since I lost my licence, I need to spend money reinforcing my desk because it won't take the weight of the new tank. I'm going for 60 gallons so my fish have plenty of space to grow for quite a while. 30 gallons each should be enough for quite a while, right?

Thanks again
