Well I thought that I had the hang of running my 29gal tank. I got all of the fin rot and pop eye cleared up I had to take all the fish back to the pet store and as soon as I did all of my others started getting better. I finished the medication and all was well, so I thought that I would get a few to replace the ones that I had to give up. So I go to the store get the fish come home put them in the water after they set there and got used to the water everything went so well the water cleared up and everything. I also put in two plants(potted Amazon Swords) Now all of a sudden I have brown/green algea so I started doing more research and found that maybe a couple of cory cats could help well I guess not enough so I went last night and got a baby pleco and a mystery snail. When I got up this morning the snail has gone to snail heaven and I'm not sure why everybody else is doing fine. I can't seem to find a whole lot of info about snails. Do you guys think that they are a good idea for my tank? All of my water parameters check fine. So now I'm at a loss again also my water has gotten real cloudy. Do you all think that I should do another water change and if so how much? Thanks for all the advice that I have received from you guys I really want to have a beautiful tank like you all have!!!! I'm just so crazy about fish love them so much*BOUNCINGS
