Hello,

i have a 60 litre tropical aquarium (at a constant temperature of 26 C) with 2 air stones. That was established for 2 weeks before adding fish and has been up and running for nearly 2 months. The fish i have are as follows;

3 mollies (1 black male, 1 white female, 1 orange black and white patched female)

2 opaline gourami (large male and small female)

1 rubber nose plecostomus

1 neon tetra (originally 5)

My one remaining neon has been getting fin nipped by my large gourami, so as of this morning has been put in a breeding tank to get a break from him and the current in the tank.

I used anti fungus and fin rot medication in the tank yesterday and removed the filter media, but woke up this morning and checked the fish as i always do and the white female molly has turned a copper/brown colour on the top half of her body, does anyone know what has caused this? I am rather worried as have never seent his before, could it be the medication?

if you know anything a reply would be greatly appreciated as the tank was a gift from my boyfriend
