Itchy Weather Loach
220 litre Freshwater Tank.
2 Sarasa Comets about 6 inches in length and 2 weather loaches. (5 inch
and 3 inch)
Cycled and established for nearly 2 years.
Had previous 130 litre for a year for them, but upgraded as tank was
too small for the four fish. Kept all the same water and cycled new
filter alongside old filter for three months until bacteria
Aqua Manta 400 external filter with carbon, sponges and ceramic.
Cleaned weekly with water changes using tank water only.
20% Water changes weekly using RO water with added minerals with part
Constant readings using Nutrafin Test Kit at:
Fed a mixture of live bloodworm, frozen bloodworm, sinking catfish
pellets, Goldfish pellets, peas and live plants.
I have noticed that one of the weather loaches is occasionally having
moments of itchiness against the bottom of the tank. No other signs of
illness. Eating normally and showing normal active behaviour.
Also one Sarasa Comet tends to head for the surface and what look's
like sucking air. No other obvious signs of ill health. Eating normally
and otherwise behaving normally.
The fish have never been ill before.
<Well, you've clearly done the important water quality checks,
which is good. I'd perhaps do a hardness test of some sort as well,
but you've done the pH, and the value of 7.6 suggests moderately
hard water, which is good for Goldfish. I would think about whether the
pH has changed though -- old tanks are prone to rapid pH drops,
especially if water changes aren't as regular as they might be, or,
more dramatically, if you rely upon calcareous media like crushed coral
to buffer the pH. "Flashing" behaviour,
when fish scratch themselves against objects, tends to mean one of
three different things: Whitespot, Velvet, and chemical irritants (such
as ammonia or nitrite) in the water. Goldfish and Weather Loaches are
both very tolerant of salt, so using the salt/heat method to treat for
Whitespot and Velvet might be worth doing, even as a precaution; use a
dose of 2 g/l and run that way for a couple of weeks. If you do water
changes, be sure to add the appropriate amount of salt to each bucket
of new water, i.e., if you take out 20 litres of water, then the new 20
litres of water will need 20 x 2 = 40 grammes of salt stirred in.
Weather Loach, beh., sys., including
goldfish -- 04/07/09
Looking for your advise please.
Sometime ago, I adopted a friends fish as she was moving overseas. They
were added to my tank. There were 2 goldfish and 1 weather loach. I
already had shubunkin and a goldfish. At the time, I did not know what
the weather loach was, as my friend was told it was a Plec (I knew it
wasn't, as I have had these
before).I went into my local fish (expert), with a photograph, and he
advised me it was a weather loach. He also advised me to buy another
one, as they live better in pairs. I did this.
One of the loach is now swimming upside down(while turning, looks like
somersaults), and when resting, laying upside down.
<Mmm, well... some of this is natural>
After reading information about them, I understand erratic swimming can
be normal, but this sort of
behaviour is not normal for him.
<Yes... considered to be "living barometers"... Changes in
air pressure seem to trigger this sort of movements>
I am concerned he is unwell, as he seems to be resting more than usual.
All the other fish are doing well, and displaying no problems.
My tank is only 2ft*1ft*1ft I believe this is (12g(U.K)),
<Oooh, way too small for this many goldfishes>
and after reading many articles on the internet, I am led to believe
this is too small for weather loach.
<This loach can be crowded... is a facultative aerial respirator and
quite tolerant to metabolite accumulation, but yes... All need more
Unfortunately, I cannot accommodate a tank any bigger. do I need to
find another home for my weather loach, or can they live in tanks this
<I'd be doing a bit more reading. Here to start:
and the linked files above... Perhaps looking into trading some of the
goldfish out, now... at least investing in test kits and their use,
along with regular water changing... Bob Fenner>
Weather Loach Not Evolving -
05/22/2006 Hi, I have 3 loaches in my tank 2 of which are the
golden variety (pink). One has befriended the grey loach and the other
is acting very strangely, it spends most of it's time resting on
top of the pump almost out of the surface of the water, and has
recently found its way onto a rock which is completely out of the
water. When he then re-enters the water it seems to be in a
state of panic splashing around franticly. I was told by an
assistant in a pet shop that he could be evolving ? < Not evolving.
May just be responding to changes in the atmospheric pressures. That is
why they are called weather loaches.-Chuck>
