sellers putting stuff in the shipping bags of fish...

[Magnum Man]

so, this kind of tags off my blue water thread... one supplier I've ordered from, puts those little pieces of absorbent foam in the bags... & I've seen sprigs of Java Moss, or similar, when shipping shrimp, to give them something to hold on to... today, I got my small gang of Cory's from Dan's, & noticed there was a chunk of what appears to be activated carbon, in each bag... yep, they were still individually packed, but each bag contained one nugget of carbon... I've bought a lot of fish from Dan's, & this is the 1st I've seen that...

it does make sense, to make the traveling fish as comfortable as possible, to increase survival rates, & hot packs have been a standard for as long as I've been mail ordering fish... the carbon seems like cheap insurance, if the fish had to spend an extra day in the bag???

anyone else use a seller that puts anything other than fish and water in the bags???

I have gotten white foam in the bag from The Wet Spot.

Carbon isn't going to do anything in a bag of fish.

We used zeolite and a small piece of neutral block when we were shipping fish that were going to spend 24 hours or more in the bag. The zeolite was used to remove ammonia from the water and the neutral block helped stop the pH dropping. We also fasted the fish for 24 hours before shipping and filled the bags with oxygen from a bottle to maximise the time the fish could stay in them.

When shipping fish we put a piece of plant in the bag for the shrimp to hang onto.

Carbon is there to absorb the fright hormone/toxins some Cory group species release. It has nothing to do with ammonia. The toxins are only released by a minority of species, but for good shippers, for the safe species, a little piece of carbon calms the customers.

Dan's fish uses carbon when shipping corys as they had an issue with them dying during shipping due to their literally poisoning themselves. The carbon prevents this. Corys are the only fish this is done as far as I know.

A lot of sellers use a little block of foam for the shrimp to hold on to.

The white foam is a piece of Polyfilter, used to absorb ammonia produced by the fish. I fast my fish for 24 hours before shipping, but always include Polyfilter as extra insurance.

Signs of a good shipper for corydoras imo, using carbon. They know their stuff on individual species groups and take care to prevent problems.

Doesn't carbon float?
If it does then it's not going to take up much if anything from the water.

These sank, and looked like carbon pellets, but were softer than what I used to use on the Tilapia filter…

I've gotten fish with Polyfilter in each bag. I appreciate the extra care from the shipper. Fasting a few days before shipping would be good but the polyfilter ensures that there is no ammonia. I can't see a bit of carbon would help much.
