Tank epidemic! Help!!

[goodeyesniper]

10g planted tank. Been up for over a year.

the other day I noticed one of my platies was sick, super skinny. I figured it was wasting disease/worms. By the time I got the medicine in (Tetra Parasite Guard), it was too late. I found him curved around the filter intake breathing heavy the next day. I did not add the second dose of medicine. I decided to temperature shock him.

Today I was looking at my tank and I discovered a neon's tail stuck inside the intake! I eventually netted him out but he ended up dying earlier tonight. Then I'm looking around my tank: 3 neons looking healthy--bright blue, swimming together. and I only see one of my platies. Still brightly colored, swimming around.

I was missing one platy which I found hiding in the deepest corner of my tank. I eventually netted him to take a closer look. His fins seemed clamp but he didn't look any skinnier than normal. I should note he was darting back and forth on the bottom of the tank.

I have no idea what's up. I cannot check my params-- I left my kit at school and I'm home for break.

The neon that died today looked like it might have curved a bit so I'm fearing it may be TB but I am not sure. picture attached.

I don't know what to do! Should I do a massive PWC and then add aquarium salt?

Do you know your parameters?

 

[goodeyesniper]

Last time I checked they were 0/0/20 but that was a month or two ago :/

 

[ktomminello]

You should definitely check your water parameters, sounds like there's something wrong there

I know, I left my master kit at school.
Oh! But i did bring home those crummy Mardel test strips. That's all I am going to be able to go on. Doesn't give an ammonia reading though.


Nitrites are 0. High alkalinity and hardness. High pH I believe.
Nitrates didn't seem to read but I doubt they're low.

How long has it been since a water change was performed?

 

[goodeyesniper]

It was 7, maybe 8 days. I just did a 50% last night and put a sponge over my intake. Hopefully that helps things

 

[foster53]

The sponge is a good idea. I do that in my fry tanks. I would try several days of water changes in a row, and see if that helps. Fish can fight off lots of ailments themselves if kept in pristine water conditions.

 

[goodeyesniper]

This might be a dumb question, but should I replace my neons so the three remaining aren't stressed during this time or should I just let them deal?

 

[Hholly]

I would just let them deal till things are straightened out.

Don't add anymore fish until this issue is solved. the 3 will be fine until then.
