Top Fin Decorations

I reported problems earlier with my fish (local, freshwater, wild fish)
flashing against various surfaces even though the water parameters appear
okay. At that time, I also pointed out that the problem seems noticeably
worse after cleaning the tank, which consists of vacuuming the gravel and
replacing the water removed.

Now, I'm noticing that when I clean the tank and temporarily pull out the
decorations that they really smell. They smell like a mix between the black
mud you find in ponds, and gasoline. I've got three large decorations in a
125 gallon tank and they all seem to smell about the same.

It could simply be that waste was trapped under or within these decorations.
But I can't help but wonder if there was some chemical reaction that was
helping to irritate my fish. I realize Top Fin is a cheap brand, but they
sell this stuff by the truckload and I would certainly have expected that
they were safe for fish.

Anyone have any thoughts on this?

interested to hear if your fish are still flashing?

Paul,

interested to hear if your fish are still flashing?

Well, I've been busy and haven't done anything to the tank for a while--I
even allowed the water level to fall a couple of inches. For the most part,
the fish have been looking a bit better with one notable exception (a green
sunfish that mostly scrapes the same location but shows no sign of
parasites), which has now been released back to the wild.

However, yesterday, I vacuumed the gravel again and top the water level off.
Although it's not too bad, my large mouth bass are definitely looking a bit
more irritated than normal.

Well... that does kinda sound weird... but my experience with plastic
plants, didn't last long... as i only used them to transition to real
plants..

I'd stop using them, period... just don't put them back...see what happens
in a couple weeks...

is that better??

RedForeman,

Actually, it isn't the plants that smell. It's larger decorations, designed
to look like pieces of wood, that smell strange.

Surely this has come up before if there is a problem. I'll try searching the
web.

I have no comments or experience with the particular product that you
have, but since these products are not required to be tested against any
mandatory safety specifications, manufacturers will (and do) try out
different suppliers. These suppliers will experiment with different
recipes for the substances used to colour and seal the product (ideally
searching for a single application, colour and sealer). Don't make too
many assumptions. If they had a bad recipe (or just made an error in
preparing a batch), or the product was improperly prepared/primed, then
the amount of bad product might not be enough to register much of a
reaction to read about on the web.

In any investigation, remove all variables and then replace them one by
one. It might be interesting to put the artificial wood in a pail with
some minnows for a few weeks. Good luck.

Yeah, I couldn't find anything. The only assumption I'm really making is
that they are selling these by the boatload and if there is a problem, I'd
expect them to find out pretty quick.

one. It might be interesting to put the artificial wood in a pail with
some minnows for a few weeks. Good luck.

I'm definitely thinking about pulling all of them out during my next water
change. Unfortunately, the tank will look pretty bare. Also, the problem is
pretty subtle and it would be hard to determine when it had in fact gone
away. Particularly since I would probably not do a 100% water change at that
time and chemicals could possibly still be in the water.

I guess I'm curious if other folks' artificial decorations (non-plants) tend
to smell strange. I don't know if that's normal or not.

Thanks.

And what do you think that they would do if they found out? Their reps
would tell the stores to refund or replace the product if anyone comes in
with a complain. What else would they do? It might have been a batch
problem, so the quantity affected might be very limited (if it's even the
artificial wood and not something else).
