Hi all, forgive the long post
been running a tropical tank for around 4 - 5 months now, its always been at its capacity stock wise but i've been very thorough with the water changes, making sure everything runs smoothly and had no losses for ages.
about 3 weeks ago, the tank got quite cloudy and there was quite a smell coming from it. First, i thought it was a bacterial bloom as i did quite a large water change a few days (but not more than 50%) and and cleaned the filter out thoroughly (and i also replaced one of the sponges).
It got progressively worse over the days and i came home to find most, if not all the fish at the top obviously in distress and i cant describe how bad the smell was. You couldnt see in the tank at all.
Strangely, my cory's and pleco seemed fine.
I therefore had to set up a very quick hospital tank, removed my tetras, glass fish, molly's and 3 clown loaches
The clown loaches came off worse, one was actually resting on top of the filter in the tank
. One was dead and another was very laboured.
Unfortunately, they have since died.
The end result of this is that i've cleaned all the tank out, new gravel etc and it is now running again (and has been for sometime) and its crystal clear
Anyone care to take a guess what happened. As i said above, the smell was really bad (and very frustrating to see fish i've had for a long time die)
thanks
