1 Danio died, another not doing well - Any thoughts
Ok, so I lost 1 danio earlier this week (Monday), tonight another one is doing poorly. I have 5 Glowlight danios and 4 white zebra danios left. The White ones have red gills and some have sorta spots on them. My two honey gouramis have reddish areas by their gills but otherwise are fine. Behavior of the tank hasn't changed at all either.
On the other hand the Rainbows I have are fine. Another possible symptom of the one that has died and the other one that is not doing well is that they are THIN, really thin.
I have posted pics at Flickr since I didn't want to resize them so you can see every possible detail to help me in figuring this out.
It's a 29G moderate planted tank, temp is steady at 79, 0 Ammonia, 0 Nitirite, 0-5 Nitrates, Ph is 7.4.
Also, the danios have been used to cycle the tank (since 1/1/07) so I don't know if that plays into it at all.
hmm it sounds a lot like ammonia poisoning, what test kit do you use?
No gasping and the danios are all over the tank except for the one that isn't doing well, he was swimming slowly at the bottom.
I agree with Musho to some extent and I believe that your test kit is in error.
Most of what you posted indicates a high ammonia concentration.
Some of what you posted indicates low oxygenation in your tank water.
An additional item is:
Have you cleaned the exterior of your tank using a chemical cleaner?
I do not know how to access the pics on Flickr.
Just click on the Flickr Link words, it's a text in an HTML url tag.
Also, I run a power head all night.
hmm, well for now use melafix to treat the wounds and help prevent a secondary infection, then try and find another lfs and ask them to test it, compare the results. Are the other fish glowlight danios or glo-fish?
I'm gonna go ahead and focus in on the fish being thin. Assuming you have been feeding them properly I would have to look to some sort of parasitic infection.
I have to agree with FD on this... it sounds more like an internal problem. If it were ammonia poisoning I would expect to see other symptoms to go with it, and other fish having problems.
How often are you feeding and what kind of food? How often are you doing water changes and how much at a time? What is the temp? Also, what does the pH read if you test your tap water right out of the tap? Is the thin fish still eating?
There are a couple of choices on meds, but that will partly depend on whether the sick fish is eating well or not...
To be honest only one of the gourami's has the reddish on by his gills, but he eats VERY well and is the dominant one between the two that I have. The only fish that seem to be affected completely are the white danios.
