Hi All,
This is really a continuation from the Sick Mollie in my son's tank
and
subsequent loss of two Mollies last weekend. I did my normal check
this
morning and now one of the Rosy Barbs is on her way out. Checked the
water
pH 8 (normal for our tanks), 0 Ammonia and Nitrites and Nitrates are at
5.

No new fish added for months. Tank has been running since last August.

Tank is around 15UK galls. Current occupants are 1 mollie and 4 Rosy
Barbs
(around 10 inches of fish maximum). Plenty of plants. Water changes
are
weekly 20-30%. We've had very few problems with this tank until now.

I just can't figure out what is going on here or what to do next. If
the
remaining Rosy Barbs would be OK with Gouramis I suppose I could move
them
and then strip down the tank - this is the only thing I can think of
for
now. But I hesitate because I don't want to risk infecting any of the
other
fish in the other tanks.

Does anyone have any clues as to what might be happening or what I can
do
next to keep the remaining fish?

Thanks
Gill

I have been reading through this problem with the fish losses. It
appears most avenues have been explored. But am I right in thinking
this tank is in a separate room from the others? Could the cause
possibly be from outside? for example, spray polish/air freshners.

You say this happens at night, is the room sealed at night? Have you
decorated recently. Open fire? gas fire/boiler
Have you had any carpets dry cleaned.
Just a few suggestions as to cause, might as well eliminate
everything.

I had a couple of losses a while ago and explored everything, did the
water changes and as a last resort before going down the chemical road
I stripped down the external filter for a good clean (Just in case). It
had only been installed for a couple of months and really did not need
the maintenence. Anyway it transpired that I had left the carbon sponge
in it for all this time, it must have been giving up and returning all
its good work back into the nice clean water! Once removed all went
back to normal and everyones happy now. Especially the cat (loads of
action going on now).
Good Luck
Please keep us posted.

Hi Steve,
Thanks for the post. There are two tanks in the room. No changes been made
to the room. Fortunately the losses seem to have stopped now and the three
remaining fish are fine.

We are still looking at redoing the tank

Thanks
Gill
