lowndsie Posted May 5, 2006 Report Share Posted May 5, 2006 My Goldfish tank has gone all cloudy. It's been established for about 2 months now and it's been getting weekly water changes. I have no idea why its suddenly gone a white cloudy colour. I've done a water change but overnite its gone back to being just as cloudy......any ideas? And now one of my goldfish is acting funny. He keeps sinking. It's a real effort for him to swim and he keeps heading up to the surface and gulping air.....any ideas? Quote Link to comment Share on other sites More sharing options...
x matt x Posted May 5, 2006 Report Share Posted May 5, 2006 Sounds like a bacteria outbreak. What size is the tank? How many goldfish? What size goldfish? What type of filter? How much water do you change weekly? How much do you feed daily? Put the sick fish in plactic container and sit it in the tank (so its away from the other fish).

lowndsie Posted May 5, 2006 Author Report Share Posted May 5, 2006 ok. its a 20 gallon tank and both the goldfish are quite small at about 3 inchs. I'm using a hang on power filter which seems to be working fine. I change about 20% every week. Before this outbreak the water had been crystal clear for ages. It could be possible that my daughter over fed them at some stage but I would of thought that a water change would of cleared it back up.

Keri Anne Posted May 5, 2006 Report Share Posted May 5, 2006 Maybe do a 50% water change and see what happens? Do you use water treatments in your water. Quote Link to comment Share on other sites More sharing options...
lowndsie Posted May 5, 2006 Author Report Share Posted May 5, 2006 I use wardley tri start and I havent had a drama since this. I'll do a 50% change now and see how I go. Quote Link to comment Share on other sites More sharing options...
x matt x Posted May 5, 2006 Report Share Posted May 5, 2006 Yeah give the gravel a vacuum & do a 50% water change. Have a look at the filter to see if it need's cleaning (Only clean it with water from the tank NOT tapwater) Goldfish that size only need to be feed 2 time aday (3 max) Quote Link to comment Share on other sites More sharing options...
lowndsie Posted May 5, 2006 Author Report Share Posted May 5, 2006 Ok. I've done a 50% change. Cleaned the filter and added an extra air stone. The water is still quite cloudy but I'll leave it overnite to see if it settles. Thanx for the info Quote Link to comment Share on other sites More sharing options...
Jo1 Posted May 5, 2006 Report Share Posted May 5, 2006 Over feeding can cause clouding. Quote Link to comment Share on other sites More sharing options...
lowndsie Posted May 5, 2006 Author Report Share Posted May 5, 2006 Yeah I think the over feeding has done it. I've noticed over the last few minutes that they just keep crapping one after the other. Obviously they are very full......of food. Quote Link to comment Share on other sites More sharing options...
Keri Anne Posted May 5, 2006 Report Share Posted May 5, 2006 You may need to do a few more water changes before things calm down. Good luck. Quote Link to comment Share on other sites More sharing options...
Caper Posted May 5, 2006 Report Share Posted May 5, 2006 Did you know that shelled peas are good for goldfish? I feed mine peas once a week. Put the sick fish in plactic container and sit it in the tank (so its away from the other fish). I didn't know you could do that? Ah, don't the other fishies just swim in? :-? :-?

lowndsie Posted May 6, 2006 Author Report Share Posted May 6, 2006 Thanx for all the info. I added a salt doasge to the tank to help the sick goldfish recover and I also placed a corner filter in as well to give a helping hand to the main filter. The result overnite is that it has cleared up almost back to crystal. And it looks like the sick goldfish has started swimming with a bit more ease to.....hopefully on his way to full recovery. Thanx again. Quote Link to comment Share on other sites More sharing options...
Keri Anne Posted May 6, 2006 Report Share Posted May 6, 2006 That's wonderful news lowndsie. I'd do another water change in 2 or 3 days to help things along. Remember that the balance (cycle) of you tank has been upset by this. Wouldn't hurt to treat it like a new tank again for a while. Maybe do 2 water changes this week and go from there?

lowndsie Posted May 6, 2006 Author Report Share Posted May 6, 2006 Yep. I recon thats good advice. Might need to explain to my daughter the benefits of not overfeeding as well.... Quote Link to comment Share on other sites More sharing options...
mustcooktea Posted May 6, 2006 Report Share Posted May 6, 2006 Like Caper, I also feed my goldfish peas once a week. They love them! I also fast them one day a week. Now that it is coming into winter it is even more important not to overfeed them if the tank is unheated. In the cooler weather their systems slow down although they will remain active. I only feed mine once a day at this time of year. I just checked the temperature of the tank today and it has dropped to 16 degree celcius with the wet weather we have had here. I hope your tank stays clear (after all we keep fish so we can look at them!). MCT Quote Link to comment Share on other sites More sharing options...

Keri Anne Posted May 7, 2006 Report Share Posted May 7, 2006 How is the tank today? Is the sick fish looking happier?? Quote Link to comment Share on other sites More sharing options...
lowndsie Posted May 7, 2006 Author Report Share Posted May 7, 2006 Yeah it is. It's still not back to full health but it seems not to be struggling as much. It's still going to the surface for air alot but it's not sinking like a stone anymore. It's a runt of a goldfish but my daughter brought it cause she felt sorry for it, so I hope it pulls through.
