Anyone coming to this event?

I know Rupert (racoll) is.

Well, Rupert made it and we went down to the show together today. Not much to see catfish-wise (I didn't expect much on that front anyway).

This was quite a talking point for the show, however. And no, it's not an optical illusion.

ouch.... clown fish, gold fish and Platy's and Guppies all toghether in the same tank....
I am sure it must have raise some good ethic discussion ...

Cheers

HH,

Any idea what they actually do for that? Or are the poor fish just suffering from being in "nearly lethal (low/high) levels of salinity"?

All that's missing is a balloon pleco. I wonder how long it is before we have veiltail marines...

They can have all the Pokemons they wan`t. I just don`t care

That was a soft launch of a product that would enable one to keep marine and freshwater fish in the same tank (there was actually more freshwater fish in the tank, including some neon tetras and a pearl gourami). I have no idea why anyone would want to do that, though.

There is also something that looks like some sort of catfish in this tank (maybe it is just a guppy). Looks like or something like that. You may see it behind the filter inlet (it is mirroring in the glass)

How this product could work? It blocks some sensores in fish or what? I just cannot imagine it.

Regards.

I'm not liking where this could lead to......

A marine fish in fresh water would tend to absorb too much water, while a freshwater fish in salt water would become dehydrated. For a product to reconcile the two, it would somehow have to help the two types of fish maintain the right osmotic balance. I would have thought that this is next to impossible, though.

Actually, I think it IS impossible

Guppy and platyfish can be adapted to life in pure marine water. Guppies can even breed there. These species looked quite OK on the picture, and I could not find other sweet water fish

There may be more in the tank, but I think these were quite unhappy indeed.

There were pearl gouramis and neon tetras also in the tank.

I can only see one marine species though, clownfish. That makes me wonder if they've found a way of keeping clownfish in fresh water. There could have been some commercial sense to this a few years ago because lots of kids wanted clownfish after seeing Finding Nemo. For example an acquaintance of mine looked into it, but got the kids orange and white goldfish instead. Close enough.

Actually in the very early 70's a similar product, Wonderwater, was being marketed for the purpose of allowing fresh and marine water fish to be kept together but it did not take off. Who would really want something like this? It was a novelty but ultimately one that doesn't work in the long run.

I don't think anyone has posted this link, pretty sure the article is about the same company:

I don't get it

why are they so hellbent on messing with nature in the south East Asian aquarium scene?

on the one hand we had so far injected glass fish ("punk fish"), dyed fish, parrot fish, glo-fish, balloon mollies, flowerhorns, tailless parrotfish, split tail betta's, tailless injected dyed parrotfish, balloon pangasius and god knows what else

on the other hand that is also the part of the world where sheer destruction of any nature on land as well as in the sea is on a rate beyond any repair.....

they HAVE to mess around with aquatic life, and in my book, none of it is good

if they would put all that "energy", money, time and resources into some serious breeding of endangered species and habitat protection, but noooo

messing about yes. protection and sensible breeding programs no.

makes me quite mad and disgusted as well.

Hey Rupert,

Have you gotten over your durian experience yet?

Maybe the durians don't like you. They're popping up all over the place again the week after you left.

No, quite possible if you select the right, sufficiently tolerant, species, and maintain them at a brackish salinity in the 10 - 15 parts per thousand range. There's an overlap in the salinity tolerance of tolerant marine and tolerant freshwater fish.

You wont be able to hold most marine inverts and practically no freshwater plants at all, and sensitive fish will over time suffer renal failure. Guppies, platies, goldfish and clownfish, however, will survive indefinitely.

Have you gotten over your durian experience yet?

Ah, the durian. The odour did linger for a couple of days afterwards as you said it would. Unique and not totally unpleasant, but sweet, fruity rotting onions is probably the closest thing I can think of. I would probably have it again, but perhaps not a whole one.

I think the salinity (SG) was about 1.010, but that it was not a regular blend of salts. They also had angel fish in there too.

Here is me enjoying the the durian and some other photos...







This crazy LFS was packed to the rafters with people, tanks, fish in bags, boxes, tubs of crabs, tubs of crayfish, crickets, worms, deities, all kinds of things. These tanks were crammed with fishes, and often hidden, obscured totally by bags of gravel. You have to catch your own fish too!







This obscene goldfish was literally the size of a football.





This photo says it all really.
