Please help! I have lost a lot of fish in the last month and I don't know why.
35G
80deg
pH-8.3
GH-3
KH-2
NO2-0.3mg/l
NH3/NH4-0mg/l
CO2-0.4
Weekly water changes (treated tap water) 25%
Tanks is 2 months old ran for 2 week pior to getting any fish.
Plastic plants, granite rocks

Current stock
3 Zera Danios
2 White Clouds
1 Harlequin Rasbora
2 Upsidedown cat fish
1 Cory Julii
1 ID shark

I have had trouble keeping fish alive. A few died here and there but in the last few weeks it is gotten really bad.

It started with 5 Gold Teras, 2 Zebra Danios, then latey 5 Harlequin Rasbora dieing from fungus? I lost a ID shark to hole in the head? A Bala shark just died along with 2 Cory Juliis.
The fish store told me I need drift wood, now my other ID shark has a white rasied dot on the base of it's tail. See picture Also has 2 other smaller dots(growths?) on it's body.

It would appear by the NO2 reading in your tank that it is still cycling.

What is your Nitrate reading? I am guessing it is at a level right now that is harmful to your fish, making them suseptable to illnesses.

Before you criticize someone walk a mile in their shoes. That way you're a mile away and you have their shoes.

That was my first guess that the tank was still in the cycling process. Did you get the water tested correctly before you started adding any fish? Live plants are far better as they will help in the cycling process. Filtration what do you have when and how do you clean it?
How did you go about cycling the tank?
Have you any airation if so increase itthis will help a little also add some Bio Started to boost your good bacteria
Finally did you put all the fish into the tank at once?

Near enough is not good enough, therefore good enough is not near enough, and only your best will do.

Hello
I took a water sample to 2 fish stores. Both gave me numbers similar to above, 1 said every thing was fine and the other said every thing was good except the ph was high. I am slowly working on lowering it.
I showed the picture to one of the stores and they said to treat the tank for fungus and sold me some medication. The fish pictured above has since died and my upsidedowncat fish will be dead in the morning but is showing no signs of illness other then floating on it's side in the tank in the top corner and rapidly breathing.
I have had an air stone in the tank since day one.
I let the tank cycle before adding fish and slowly added fish a few each week.
I am wondering if my problem isn't something toxic in the tank? The plants and gravel all came from the the fish store and were rinsed but my rocks are from the garden. I have slate and granite/marble. I tested every rock with vinigar and they didn't bubble, so i rinsed them and put them in.

Stephen

but my rocks are from the garden

Saying that could be your problem. You would have no idea what has been used and sprayed in and around those rocks or just contaminated from the garden. If they are porus at all any nastie could still be leaching out of the rocks.

I would tank them out and buy suitable ones from your LFS.

If using rocks from your garden(any where actually) you have to throughly scrub them and soak them without any detergents and what not.

I think that the tank may still be cyclign also...

10G- 6 Zebra Danios, 1 Upside Down Catfish
20G- 1 Goldfish
72G(maybe95)- Need Stock suggestions

If the tap water is at lower pH, im alost sure one/some of those rocks are carbonates that somehow passed the vinegar test! Marble is calcium carbonate! may be some layer of salt/oxide develoved on them prevented the vinegar from reacting and now that its gone, the carbonated are doing their job...
