Fish are dying daily. Help please?

[Philly33]

I have a heavily planted 90gal med light non co2 (just liquid carbon and liquid ferts). 45% pwc, all water parameters are good.
Over a months time I've added harlequin rasporas and celestial pearl danios. Slowly I've lost a siamensis, panda garra loach, cherry shrimp, and the rasporas/danios have been dying daily.

HELP PLEASE!!!!!

I'm sorry about your fish. Can you give us a little more info like parameters? Also are the fish looking ill then dying or just dying out of nowhere? Do they have any signs like odd breathing, clamped fins, fuzzy growth, spots, change in color, etc?

You should probably give more details so people can get a picture of what is going on in your tank. Is it cycled? For how long? What are exact parameters? Temp? New additions? Symptoms? Help us help you.

I've tested for ammonia, nitrate, nitrite all good. Even had it tested at my LFS, all good. The new additions are the harlequin and CPDs. The harlequins look like a cloudy film, the loach had a red spot near its gill, the siamensis had a spot/sore on its belly. I'm guilty of not having a quarantine tank. The tank has been fully cycled for 16 months. Temp 76

What is being used to test? Strips or liquid?

 

[Philly33]

Liquid. Zeros for ammonia, nitrate/nitrite

Ok. Are they acting ill for a few days or just dropping? Is the white film all over or just around the gills or mouth. Anything sticking out of the red bumps? Any flashing?

Just dropping like flies. Can they die from over consumption of food? I've never had tiny fish like this before and may be over feeding. Can it also be a gastro problem? I extract any uneaten food, so it's not food decomposition.

They can die from constipation from over feeding but I would expect to loose one or two not that many. Are they bloated before they die?
Had anything new been added to the tank? Anything sprayed near the tank? Change in food? Chemicals in PWC buckets?
It sounds like something was brought in with the new fish like a virus, bacteria or parasite. We need to pin point what.

Could try raising the temp slowly to about 80 and see how that goes. You could also try dosing melafix as well to see if that helps any. Pictures would help if u could get any. If it's due to overfeeding maybe feed every 2nd day and try and supplement spiraluna into their diet.

I'm noticing fin rot and cottonlike fungus, ugh! I was able to get a close up today. 2 more casualties.

What are the potential causes?

maracyn and maracyn 2 are my next step.

Thanks everyone

Sounds like columnaris to me. Please google and compare the pics to what you see.

When I came across it in my tank, I culled the two symptomatic fish, did a 50% water change and dosed at half-dosage with aquarium salt.

Columnaris is highly contagious. If you don't take very drastic measures, you may lose everyone.

Read this thread. I agree it sound like columnaris. It moves fast and can kill of entire tanks. You need a gram negative antibiotic to treat.

Thanks. You hit the nail on the head. I'm dosing Maracyn 2. Do I have to reduce my lighting? I read a thread that mentioned it. It didn't mention that in the directions.
