I agree Intravenous, by bashing him everytime he says anything, you are just going to make him leave the site, and then how are we going to help him? He's very uneducated about fish, which I'm sure most of us were when we were that age, but the only way to help him is to give him advice, and most of the previous posts didn't contain any advice. An acorn doesn't turn into an oak tree overnight, give the kid some time. He's only been on this site for what, a month, and everyones harping on him because he hasn't fixed his tank since he was told to, which was like last week!
Coolfish ~ How old are you anyways? How are we supposed to help you if you don't tell us the truth? When you posted pics of your gouramis, I told you that the water was yellow. You insisted that it wasn't and your water was perfect, but the flash made it look yellow. The first step in getting help is admitting that there is a problem. Obviously, from the looks of your tank, there is a problem.
So, what fish do you HAVE to keep and what fish can you stand to let go? You really need to decide between the clown loaches or plecos, you cannot keep them both in a tank that small. You really shouldn't keep either, but if you can get rid of one that would be better than nothing. And do you really need all of those mollies?
From now on, start doing daily water changes. Take about 30% of the water out each day and add fresh, dechlorinated water. That will help with your water quality problems (fin rot, ich) And absolutely positively do NOT add anymore fish! And save your money, then you can buy yourself a bigger tank. It's time to grow up and be responsible, you can't rely on your parents forever and taking care of an aquarium, and keeping your fish healthy is a good way to start.
