Hi everyone,

I purchased a young F8 puffer yesterday and he is in a fresh water tank at the moment, I am aware that in the long term it is best to keep F8's in low end brackish water so I would like to have him in low end brackish water in the next 6 months.

Please can I get some advice on how much salt I would need to add to my 100litre tank so that the water is low end brackish?
A 50% water change is done every week so also how much salt would I need to add to the water I add when doing the water change?

Here is a picture of the tank and the little puffer :)

All help/advice much apreaciated :good:
 
Given you want to grow plants as well, your aim is SG 1.002-1.003 at 25 C; that's about 5-6 grammes of marine aquarium salt mix per litre of water. In other words, 500-600 grammes for a 100 litre aquarium (though in all likelihood your tank contains rather less than this, maybe 90 litres, if you account for the rocks, gravel, etc., so you might want to reduce the amount of salt mentioned by about 10%, i.e., 450-540 grammes.

The sooner you switch to brackish, the better. At this very low salinity, you can actually mix up all the salt you need into a jug of water, and then pour it into the tank across an hour. That'll give your plants and filter bacteria time enough to adapt.

Cheers, Neale
 
Glad to help. But if you want more puffer stuff in PFK, you need to let the editor know! Jeremy Gay is the chap who commissions the articles.

As it happens, I have a couple of pieces coming up in PFK, but neither are about puffers. :-(

Cheers, Neale

Great advice Neale. I wish you covered more about Puffers in PFK.
 
May go and inundate him with emails then :lol:

Look forward to reading them Neale... Good i hope?
 
Thanks for the advice,

A stupid question here, will adding salt have any adverse effect on any of the plants/moss in the tank?
And would you recommend any type of aquarium salt (I guess as long as its aquarium salt it will be fine)

By adding salt to the aquarium will I need to do anything else (maintenence wise) other that I would normally do with my freshwater tanks?

Thanks again and happy Christmas :good:
 
Not for me to say. But I think the editor liked them.

To be honest, the problem for all the fishkeeping magazines is getting the balance between detailed articles for those 5% of the readers who keep oddballs and other rare fish, and the 95% of them who keep mainstream stuff like community tanks and reef tanks. Once people become "serious" hobbyists, they often stop reading the magazines because there aren't enough articles about the unusual fish, so a magazine has to concentrate on the things casual hobbyists enjoy. It's a really difficult balance to get right, even for the successful magazines that have been in business for decades.

In the old days you either read a magazine like PFK or else if you wanted something more specific, you joined a club (like the British Cichlid Association, for example) that supplied you with a magazine every few months focused on your specific interest. But now with the internet it's easy for someone to stop reading a magazine and instead go read articles on the most obscure topics on some web site instead. Magazines are finding it hard to keep the readers they have, let alone get new ones.

That's a shame in many ways, but the biggest downside to the freedom of the internet is the lack of consistency. It's never easy to be sure if what you're reading is done by an expert, by someone who plagiarises other web sites without fact checking, or else the site was done by someone who didn't have a clue what they were talking about. At least with a magazine there will have been an editor who will have read through the article and made sure it was commissioned from somebody who had a reasonable grasp of the subject at hand.

On the other hand, there are, for example, three or four really expert pufferfish keepers I know from their work on forums who have gone on to write magazine articles. So if magazine editors keep an eye on web sites and forums, it's possible for them recruit excellent new writers. Another case in point: I believe that George Farmer was an active member on this site for some time before he started writing regularly for PFK magazine on planted aquaria.

Cheers, Neale

Look forward to reading them Neale... Good i hope?

The stupid question is the one that isn't asked.

No, this low level of salinity won't harm your plants. Or at least, it won't harm hardy, hard water tolerant plants such as Vallisneria, Java fern, Java moss, Hygrophila, Amazon swords, Cryptocoryne wendtii, to name but a few. You do have a few red plants there like Rotala that are difficult to grow at the best of times, and I'd predict failure in that tank even without the salt, unless you have soft water, CO2 fertilisations, and very strong lighting. The salt would merely hasten their demise.

A stupid question here, will adding salt have any adverse effect on any of the plants/moss in the tank? And would you recommend any type of aquarium salt (I guess as long as its aquarium salt it will be fine)
 
Thanks,

I am still learning with the plants so the way I do it is chuck them in and if/when they die pull them out and add more of what is is not dieing :lol:

Also the water round my area is super hard so that wont help the cause.
 
Quite so. Well, if you choose from the plants mentioned above, as well as other hard water species, you're laughing! Elodea for example prefers hard water, and Cryptocoryne ciliata is actually prefers brackish water in the wild! So you do have some options, and these species are often less fussy about CO2 because they can use dissolved carbonate hardness instead. It's a win/win situation -- choose hard water plants, and you'll be happy and they'll be happy!

Cheers, Neale

PS. Looking at your tank, why not try this: Put Amazon swords and Vallisneria around the back. Get some potted Cryptocoryne wendtii for the middle ground on either side. Some Java fern, Java moss, and Anubias on boogwood and coconut shells for the centre. Add a few nondescript seashells to provide a slightly marine feel, e.g., some mussels or oysters. Perfect suggestion of a rainforest stream near the sea that gets an occasional high tide washing some salt in. Prime puffer and goby habitat!

I believe you need Marine Aquarium salt rather than just normal Aquarium salt?

Plants usually do ok with the levels you need but high end brackish and not very much survives at all.

I'm glad my 3 are freshwater :lol:

Neale, what you write is very true... But i still buy the magazine as i find the majority of it to be of interest. (Not that fussed about marine... yet!)

I would say there is enough species of puffers to do an article on them, a little like they have done with pike cichlids, dwarf pike cichlids, snakeheads, dwarf snakeheads etc. :unsure:

And for sure, there is plenty of info on the net about puffers, but alot of it is very conflicting so a little unsure on what to believe. I have read your articles on WWM regarding SAP's and i kind of run with this as i know you know your stuff. lol.

Sounds like a plan, I will have to move everything round in the new year when I add a second F8 puffer, so that gives me time to get all the other decor sorted.

I just fed the Puffer and by god he is a messy eater, a lot of the fish I fed him is left sitting on the sand so will have to hoover the bits out now! he has a big fat belly now aswell.
 
I did tell you not to feed alot at once... :rolleyes:


Haha it was not a case of how much I fed, but a case of the little #29### tearing pieces off and spitting some out.
 
Absolutely. A little but often. And do use mostly stuff with shells on, like krill or frozen brine shrimp. Even if you forget about the beak (this species isn't too bad on that front) the "roughage" helps puffers fill up quickly, without massively increasing ammonia concentration. Remember, with puffers, nitrate is the enemy, so you want as little ammonia as possible feeding into the biological filter.

Cheers, Neale

PS. As for salt, yes, marine aquarium salt mix. You'll notice that's what I said in my original reply! Aquarium salt is fine for a few months if that's what you have. Use it up, by all means. But when it's done, use the marine aquarium salt mix.
