Help - what's wrong with my firefish?

Hi - I have had my firefish for about 4 weeks now, and it was doing good. Did a water quality test at my lfs on Sunday, and my nitrates were at 160ppm, and salinity at 1.025. LFS recommended a 25% water change with only r/o water, provided by them. I did that, and salinity dropped to 1.019, but nitrate remained at 160. Did 1 more 1litre water change, but still no change in nitrates. This morning, fish is hanging at front of tank - usually it hides in its cave under rock, and not interested in feeding. Is this ick?
My tank is a Fluval Edge (6 gallon).
I should add that I got a feather duster from LFS on Saturday - all water parameters were fine then- only deteriorated after the duster.

160ppm Nitrate is probably the orignal cause. Then, dropping salinty so far so quickly has likely made the issue much worse.

Did you mix the salt right for the 25% PWC? It almost sounds like you used fresh water for the PWC with no salt in it.

You need to take the fish back until you figure out why your nitrates are so crazy high, and you cant just do a 100% PWC all at once either. (With the fish still in the tank)

This LFS told you to do a water change with plain RO? Whaatttt.
Your salt levels were perfect. As mrg02g said, Sudden salinty changes would of caused stress and the nitrates are bad, Not helping anything.

I recomend slowing topping up the tank with saltwater untill you reach 1.025 again, And do a 30% water change every 3 hours untill you have reached 0nitrate or close too.

Thanks guys - I have started with 25% water change (SALT WATER) and will repeat over the next few days until salinity reaches 1.025 again.
I will definitely NOT be taking advice from LFS henceforth!!!!
Their advice - feed 2x daily, and when nitrates shot up, 25% water change using pure r/o water (no salt). Hmm.

Do not feed 2x daily either. Another piece of bad advice, unless you got anthias or something that require more frequent feeding. Heck, a lot of us feed once every other day. On the SW PWCs.... if you're trying to elevate the salinity, be careful to ony try to raise it about .001 daily so you won't stress the fish with sudden salinty swings - either up or down.

To answer the questions about Ich, yes he has it. It's probably a result of the stress of the sudden salinity swings. What your going to have to do now is QT him and do either a hyposalinty treatment or a copper dosage to clean him up and make him healthy. Also since ich is present in your main tank now, it should remain fishless for about 6-8 weeks to break the ichs life cycle to prevent further infections down the road with other fish. If you don't then you run the risk of infecting every fish you put in there and that can cause you to lose all your livestock.

Sorry to hear you got such bad advice from your LFS. Sometimes I think they just make stuff up when they don't know.

Im willing to bet the lfs thinks you have a freshwater tank. Everything would make better sense then.


I would suggest the copper based ich treatment unless you have a refractometer. Hyposalinty requires precision.

Once in quarantine, do a huge water change on the main tank unless you have more critters in it.

The frequent (over feedings) likely contributed to the high nitrates for the most part. Now you know.

From now on, come here for all your questions.

It sounded like the LFS was telling you to use their RO/DI water instead of "TAP" water for your water changes. Of course you would still have to mix that "Water" with a saltmix to do your water changes.

I think thincat has the right theory. Theres no way a LFS could remain a LFS for more than one day if they were using freshwater for their PWCs and not using any salt.

There are alot of crappy LFSs out there, but they at least know what they are doing. (Well, enough to keep fish looking good enough to buy).

Make sure to let us know how things turn out. Also, make sure you mix your salt water outside the main tank to avoid caustic burns (from undissolved salt) on the critters in the main tank.
