Wierd.. but whaqts the explanation of...

[T]

I read the article about Oscars getting HTH... Ones of the suggested
causes for this is supposed to be Activated Carbon in the filters??? Anyone
have a clue on why this might affect Oscars?? I have never had a case of HTH
with Africans nor with Convicts... the only thing I have noticed is if I
slip and miss water changes this seems to be the factor in HTH... As
mentioned my last Oscar developed HTH but this fellow was feed a great
varied diet... Tetra Min Flake, Hikari pellets, fresh skin free peas, fresh
disease free guppies ( these I breed and raise myself as I refuse to use LFS
feeders..) and at times for a snack I would toss in a horizontal slice of
orange ( the tank mates Koi really enjoy this snack ) which the Oscar would
pick at... I run two AC 300's on a 55USG tank, along with a 401 PH with the
cartridge style filter ( this is enough filtration for a 200+ USG tank ).
And as mentioned I had a sub adult Oscar get HTH... What gives??????

carbon might remove some things that the fish needs (possibly vitamins,
minerals, etc) lack of which could be a cause of hith. I guess its effects
are not natural for the fish.

I guess its possible, but another thought I had, was perhaps these Oscars,
should maybe not be kept as a tank inhabitant then??? When I see people
buying Pacu's, TF barbs, red tail catfish, and other larger size fish I
often wonder what becomes if these critters.... ( much like the arrowana's I
see at the LFS yesterday, 2ft long and growing.. Cute when they are small
but grow very fast...) This is just food for thought..

Timmer,

I think part of the problem could be your tank set-up. While you seem to
have an excellent water filtration system, oscars produce an awful lot of
waste (more so than other large cichlids). A 55 gallon would be sufficient
for a single oscar, however you mention you keep Koi in the same aquarium.
Koi grow to exceptionally large sizes, and are more suited for a pond
environment. In addition, Koi are a "cold" water fish, while oscars (and
cichlids in general) are "warm" water fish. I would recommend keeping the
oscar in its own tank where you can maintain proper water conditions for
this species, while not having to worry about the extra biological load
produced my the Koi. This is my opinion only YMMV.

Hope this helps,

Robert C. Hedley

Hey Robert,

I would agree that the Koi may have affectted the water conditions, (
nothing like keeping 4 groups of high waste fish in one tank Oscars Koi GF
and a Pl*co ) . But I managed to get rid of the first bout of HTH even with
the rest of the fish in the tank. I know recently I did do a carbon change
in the filters. Unfortuanatly I have sold all the fish from this tank as I
have to move... What I did notice while I was taking the tank down was in
the filters... I took the carbon bags out and noticed as I rinsed them there
was in fact some carbon residue coming from these media bags. I swear before
I put them into the filter I rinsed them until all the carbon dust
disappeared.. Perhaps there is something with the carbon dust that
contributes to the problem..??? I know it has been suggested that as varied
diet helps, but I don't think this was the case this time...This is
certainly an intresting discussion.. ( I didn't mention that the smaller 2
Oscars never had it ).. Great topic ... Great thread...

Tim..
