I'm a newbie. Unsure about my fish. Behaving blindly?
« on: April 15, 2012, 01:27:10 AM »

Hi! Any suggestions, tips, or knowledge about this would be greatly appreciated! Smiley

1. How big is your tank: ~25 Gal

2. For how long has the tank been set up: 9 months

3. How many fish: 4 (I know the tank is too small. Sad working on getting a bigger tank setup.)

4. What kind of fish: feeder/goldfish

5. What are the water parameters:
Ammonia = 0
Nitrite = 0
Nitrate = 0
Ph = 7-7.5
Temp = 20C

6. How often do you perform water changes: almost weekly. Sometimes a few days late.

7. How big are your waterchanges: 25-30%

8. What kind of waterconditioner are you using: Nutrafin aqua plus. Sometimes API stresscoat

9. Do you add beneficial bacteria: every 1-2 water changes

10. Symptoms your fish is showing: they seem to be swimming around and bumping into things (glass, plants, each other). It was dark when I got home, I had no lights on and when turning on the lights they didn't seem to see me. I fed them, but they didn't swim to the surface to eat. They just hovered the ground feeding off the gravel and bumping into things. The make fish would attempt to chase the females, nudging their behind (like normal) but they's stop because they swam into a,plant or made contact with the glass. I don't see any spots, fin rot, or worms. No cuts or various bulges. No visible air pockets behind the eyes though it may look like their eyes could be puffy... (they don't look like any of the popeyed fish I googled.) they didn't react to fast movement coming at them through the glass. They ate when they found the food at the bottom of the tank. They released a few bubbles that rose to the surface, they found those thinking it was food after about an hour of leaving the light on for them. Haven't seen them poop yet...

11. Since when does your fish show these symptoms: just tonight.

12. How is the normal behaviour of your fish: they typically greet me when I enter the room, swimming into the front part of the tank, "feed me! Feed me! Feed me!" All excited. The swim around, roam the bottom for left overs and chase each other around the tank. Very active fish, happy looking fish.

13. How do the other fish behave: all the same. Happy and active; chasing and grazing the rocks. Now they all seem to be doing the same thing.

14. Post pics of the sick fish: sorry for the bad quality. The tank light is off and I had limited lighting.

15. Do you have a filter on your tank, what kind, how big (gallons per hour). Its a Cascade 150 for 35 gals. Pumped 150 g.p.h.

16. Do you provide extra aeration with an air pump and air stone/diffuser of some kind? Don't think so...

Many thanks!

Hi Mellah and welcome to the forum.

It could be, that switching on the light, dazzled the fish in some manner.
I once came home and switched on my bedroom light to find I'd woken her up, she was rather confused and didn't come to the surface when I tried to feed her.

So unless they are constantly bumping into things, during the day/when it's light, I would think they were just a little confused Wink

Also, I see you mention that you are considering a larger set up, as by the looks of things you have 4 common goldfish there.
I put together a little article about housing such fish (myself I own a common goldfish and I'm in the same situation) so it may help you with deciding on a larger set up (Link is not visible to guests. Please register to view.)

Best of luck, hope the fish are okay!

Just to be safe, I'd change a little bit of water whenever they would act like this since it's usually a sign that something might be wrong with the water quality. Especially since the tank is a bit small and slightly under-filtered.
It might be a good idea to start changing out 50% with every water change from now on Smiley Please keep us updated in case you notice this kind of behavior again Smiley

You have beautiful fish, Mel.

They look pretty healthy to me, though of course this doesn't necessarily mean there isn't something wrong internally. From the pictures, the water does look a tiny bit cloudy though.

As others have mentioned, it could just be the suddenness of turning on the light. I usually wait at least 30 minutes or so after I turn the light on to feed my goldfish so that their eyes can adjust first. Also, since you're tank is already overcrowded, you would probably do best with more frequent water changes. Maybe try changing the water every 5 days or so, taking out 30-50% each water change? It might help clear up the water. You can even throw in an airstone for added oxygen until you're ready to upgrade.

Of course, continue to monitor the water, and let us know if something else comes up.
