6 goldfish all at bottom of tank laying on their sides
Help! Last week we noticed our 7 goldfish and 5 swordtails sort of swimming around the filter. We didn't think much of it but I started losing fish. Yesterday all the fish were doing were laying on their sides in the fake plants. I can get the net and they will move and then sink down to the bottom. It's a 55 gal tank, we did a 2/3 water change and I stopped by pet store and got a poly filter which they said to use for 12 hours and then take it out and put in this type of fungus remover than cures costiasis, dropsy, hemoragic septicemia, etc. and take out the carbon filters. The fish do appear to have little holes in their sides which sounded like Spring Virosis from your info. Don't know but it is just pitiful. I have had the poly filter in for about 5 hours and no change. We did wait 3 months to gravel vac this time and we added 5 swordtails last month from a friend. The amonia and nitrate and nitrate levels are reading fine, water tem 72 degrees. Haven't put the antibiotic in yet, hopefully someone will help me here before they all die. Many thanks!
