Answer 1

Lots of things are wrong
1. You are feeding too much. The worms are thriving from left over food. When you saw them you should have stopped feeding your fish and waited for them to eat them. The you could resume feeding them at half of what you are used to.
2. Your feeding too much has caused the water parameters to go off. The spikes in nitrites and ammonia are toxic to your fish as well and the spikes happening constantly from feeding to much weaken you fish and leave them susceptible to other problems.
3. Your cleaning the whole tank is just as bad as leaving it dirty - and it sent them into shock. NEVER change more then half of the water. Buy a gravel siphon and change 25% of the water once a week with aged tap water that is the same temp of the tank.

Read around on some fish forums on how to properly set up, care for, and maintain fish in aquariums. Research the types of fish you want also before you buy them to make sure they won't outgrow your tank, or most likely die before they do outgrow it. First thing you need to do is cycle the tank. You also need to do regular weekly water changes. Not sure what kind of plecos you have, if they're the common ones, they're not compatible with a 20 gallon tank, and you really shouldn't have had 2 in there. The worms are probably planaria, which usually show up when you overfeed your fish. Try doing a 50% water change right now to try and save the remaining fish. Be sure to use dechlorinator in the new water to eliminate the chlorine or chloramine from the tap water. As I said, I strongly suggest doing a little research, these sites will help you. Just read through all the posts, especially cycling a fish tank.

Answer 3

I had a fish in a tank with rocks/(fake)plants one time and then he died, I thought I cleaned the tank decently and got another fish, that died shortly after that, and another..... then I heard that when one fish dies in a tank (especially if it was sick), the bacteria could be stuck in the rocks, even after you think you've cleaned it, and bacteria is worse if the fish is in there dead for a while. My best advice is to get rid of all the rocks/plants clean the tank reallyreally good and rinse it really good and buy all new fish and scenery.

Answer 4

Well just start from the beginning. Fill the tank and let it filter 24 hours. Then add some Aquasafe, test the amonia, ph, and nitrate levels. Balance the ph. You should add about 2 hardy fish, such as guppies, platies, any livebearing fish to get the bacteria cyle to start. Once the tank has cycled (ph is at about 7, amonia and nitrate are 0) you can add more fish. See http://www.petco.com/caresheets/fish/SetUpFreshwaterAquarium.pdf

Answer 5

you dident explain what species of fishes you had other than the sucker mouth catfish, in reality they are easy to kill. you need to get your water tested for ph and nitrates and nitrites. did you check your fish for white spots, did you examin the fish to see if their was any deformities or anything like that? those worms were from over feeding, it is vary common for people to over feed their fish. the fishes could be eating all the food you put in but it still is over eating. most people buy fish from wal-mart, petco, or PetSmart... these plases usualy have sick fish. use decloranator when you put new water in and no matter what never use soap or bleach for anything in your aquarium unless you know what you are doing with bleach and you bleach shells(i dont advise it)

Answer 6

u need to convert the bad chemicals in the tap water by using some product that u put in the filter, it helps change the bad chemicals to good chemicals something to do with carbon. then u can put ur fishys in the aquarium.

Answer 7

Did you treat your water after cleaning out the bottom? If you didn't then they most likely were killed by Chlorine.

Answer 8

Just so you know, the singular and plural is fish and it's spelled die. I can't actually help w/ your question, I'm just a thoughtful bloke, who aims to educate people when I can.

Answer 9

you didn't pull the fish out of the water, even for a second, did you? The reason why I ask is, I used to do that to our fish when I was a little kid, and they all died.

Answer 10

if u never want your fish to die.
then the best way to avoid that would be dont buy fish.
i wouldnt have any kids if i were you.
