Tank Not Happy

[sallynryan]

My 60 litre tank has been set up for about 5 months and have built up fish gradually I now have about 12 ranging from neon tetras to a honey gurami. On monday i put 2 new mollies in and found 1 dead upside down under an ornament on tues morning. I thought nothing of this as I have had no other problems so thought maybe it was just stress but now by bottom cleaner has been lying on its side for over 12 hours and I have turned it but just goes back on its side and all my other fish seem aggitated and are going at each other. Any clues anyone? Would be grateful for any suggestions or comments

You need to find your water statistics otherwise no one can help you.
 
First thing to do is a large water change, at least 50%. You may have experienced a mini-cycle wherein your ammonia level has risen. Water change though, do it now.

Yes you need to test your water, with that information people are more able to offer advice.

I would also agree with shiny, after any fish loss a large water change won't do any harm.

The first question I would ask is when you brought home the new fish did you pour the bag water into the tank?

Don't you just hate it when someone just signs up, pops in, asks a question and never replies, never acknowledges people's input and never reappears?

Not everyone can be one here often....
