hi all, thught i would join as i need some advice. i have kept godfish in a tank for years and had no problems. so last summer i thought it would be nice to start a tropical tank. its something ive always wanted to do. so i thought long and hard and read a few good books, spoke to a friend who has tropical fish. and browsed the hinternet. i then started to save to go for it. well to cut a long story short, i finally bought a tank starter kit,(a combined birthday and xmas present from friends and family) which came with the tank an elite pump and heater. i set the tank up and followed the instructions adding the biological starter and ran the tank for a mth. after that i got the water tested and it was apparently perfect, so i purchased my first 2 fish. 2 lovely little bronze corydoras. they did ok for the first 2 weeks then i got 2 pepper doras. my intention was to have them for a bit them get some tetras. i wasnt intending to be too adventurous as i am a beginner and i dont have a lot to spend on buying lots of fish. i already have 4 dogs, 3 cats, 1 guinea pig and the 4 goldies, and it is just little old me here. anyway the problems began this week. ive had the bronze for a month and the peppers for 2 weeks. on mon i noticed the little pepper didnt seem well, he/she was hanging about under the rocks and wouldnt feed. it was very hard to look at properly as he just wanted to hide. anyway tues morn i got a prper look and i noticed there was damage to the tail, my first thought was oh no fin rot. i checked the others and at that point they looked fine. i must admit stupid idiot that i am i didnt rush out to get treatment as i wasnt sure and i just didnt have time (i know, i know i am a bad fish mum and i was asking for what i got). tues night the little pepper was floating upside down. within 2 days the bronzes had both died as well. they definatly im sure had fin rot and one also had fungus that cotton wool type one. i feel terrible about it as they seemed to be doing so well till this week. the larger pepper is still here and he is showing no signs, he seems fine but im worried it might succumb too. i did a water change on wednesday and added the water conditioner. i now dont know what to do. do i go out and get some treatment anyway and if so what. do i leave pepper on his own for a couple of weeks before i start again. i know i must definatly quarentine this time, yes i know i should have done that with the peppers but i dont have a spare tank, the little one i had got damaged so had to be thrown away. it is on my list of kit but i can only buy a bit at a time. and i guess i would need a spare heater and pump as well. im begining to think maybe i should have stuck with the goldies now but i really would love to have a nice tropical tank. it sits at the end of my bed and as i have to lay down a lot cause of my disability it gives me something to watch and enjoy. tv is so boring. i really want to get this right. the fish deserve it first and foremost . so any advice for me please. thanks so much tracey
