Hi folks - I have a golden molly that has been acting a little funny and I'm worried. I've found him a couple of times "resting" at the bottom of the tank. He's been on his abdomen, flipping fins just a little - not on his side. He may also be looking thinner... hard to say.

This most recent time I was away for two days and he was on the bottom when I came home. Ammonia and nitrites are 0 but nitrates are at 20ppm. I did a 50% water change. He came to the top to eat and has been swimming around.

In the last couple of weeks, here are the new things I've done: I did start adding a little bit of aquarium salt to my tank (2 tbs for my 10g tank - and then adding 1/2 tsp/gallon when I do water changes). I also added hornwort because my other molly seems to be pregnant and I was trying to add hiding places for her fry. Finally, I added a nerite snail.

I use seachem prime at water changes and tropical fish flake food once a day. I occasionally break up an algae wafer and put it in. The tank has a gravel substrate, 6 plants, 2 mollies and 3 danios. My tank runs cool (76-78 degrees -pre-set heater)

I don't have a qt :(

Help!
 
I'm not an expert but the salt might help him out. I had my mollies in brackish water and they loved it. I hear pet mollies don't need brackish water but mine appreciated it, so I'm sure the salt will help your little fish.

I hope someone can help you further. Mollies are such adorable fish.


Katanas - because swords are awesome! (Even swordtails!)
 
Thanks. I added a small amount of aquarium salt but he just got worse and worse and eventually died :( I tried to buy a treatment at the LFS but the clerk insisted that I shouldn't treat him unless I had a good idea of what I was trying to treat... I should have insisted.
