Hello,
We have a silver molly that has been in our tank for about a year, and we have noticed that in the past 6 months or so, a black outline had been on his tail. I assume this is some sort of burn, and today when we added another molly, its tail immediately got a black outline similar to the other fish.
This is our most recent water testing:
I assume it corresponds with this key (Note that the test strip in the below picture is not ours, it is from a key I found on the internet!):
The tank itself:
Molly black fins (Sorry for the blurriness of some of them):
Hard to see the outline in this one, but it seems just barely visible:
There has also been issues with 1-2 centimeter cotton ball-like things floating in the water when we clean it. (It almost looks like mold.) Unfortunately I do not have a picture of this at the moment though.
Some statistics, we have a 10G tank with currently 6 fish (2 guppies, 3 mollies, 1 tetra). We normally do water changes once every 1-2 weeks, and change about 45% of the water out, and we have never did a full water change. We are using the stock filter and are trying to change that more often (Once every 2 weeks or so).
Some general questions:
- Does anything we are doing currently sound bad?
- How much should we feed the fish? - we've been told over the phone by Petsmart that feeding them as much as their eye is good, as well as the website telling us as much as they can eat in 2-3 minutes.
- When fish were put into the tank, we were told they let off chemicals, which doesn't make sense to us, is that true?
Thanks in advance,
- Mario
