I recently purchased my first tank as well as fish, a few days ago. currently I have gold fish, black moore and shunbunkins and algae eaters. but my question problem is that I set up the tank as directed to a "T" then one by one added my fish to the tank, which soon turned so murky that you could barely see the fish. So reading the book, as directed I cleaned the tank from top to bottom, using no chemicals what so ever. cleaned the gravel, fake plants. put the fish back in again and the same thing happened all over. (booklet failed to mention all the balances that occures and what to do :-[) called the local petsmart store and they said that the tank could be over crowded, 10gal 6 fish all about 2 in long. so I go and get antoher tank and put half in it, after carefully reading teh instructions. but the same thing happend, clowdy water (lost one fish :'() so I read on here about a partial water change. I did a partial water change but have yet to put my fish back in the water. (or was I supposed to leave them in the water when doing a partial water change) would this bother them by doing it every day till the tank settles and gets normal? I will be getting a water test kit this weekend so I can better monitor the water. Also do you think 5 fish will be ok for a 10 gal tank? My husband wants to use the other tank for tropical fish so we are getting it ready for them, letting it cycle for a few days before getting fish. Any suggestions would be grateful. I have read and researched ever since I got the fish, baught a book on tropical nad fresh water fish, and read till by eyes burned. ;D. Oh I currently have my fish in a smaller "quarintine" tank, is that ok? ???
