Hi Sal,
Welcome to the fold, err I mean Forum.... heh... yeahh...
This whole thing has ended up as quite the obsession for little ol' me, and I'm sure there are plenty of other members here that can attest to the addictive nature of fishkeeping.
My introduction to this forum was a quiet one until I learnt about the perils of fin rot, however with the Aus Aqua brains trust I was able to identify and treat it, and in-turn - became more au-fait with rot that I'd like to be!
There's a pretty steep learning curve with the betta, and working out water chemistry is actually kind of tricky... I still only just get how a tank cycles - on principal.
It sounds like you'll need to wrap yourself around a few water principals, and you should be right after that....
Fortunately there's a few things you can do to ensure betta happiness in a tank, even if it's a smaller tank.
The water parameters are the key to everything, and while there is a bit of room to move with these - Betta really like stability.
- Firstly temperature, ideally between 24-28 degrees. (mine are stable at 26 at all times, 28 if I'm breeding)
- Ph from either 6.5 - 7.5 but the key is stability (water out of the tap swings in PH as it oxidises - therefore having a KZ buffer really helps)
- De chlorinated / conditioned water (water that is out of the tap and left will actually de-chlorinate naturally as it oxidises, but if you want to use water instantly, you can use a dechlorinator, which is a good idea, as it primes the water and often has minerals and goodies to keep fish healthy)
- Carbonate Hardness (this is my faaaaaaavourite thing in the world as it was such an epiphany when I learnt about it)
It's a good thing to get your water tested for - you might have a nice PH but if your carbonate hardess is out, fin rot and the rest will follow.
I buy a slightly pricey powder from Aquapix called Carbonate hardness buffer and it keeps my PH at 7 always, and my hardness is perfecto. Haven't had rot since = WIN
As for things you can add to the water....
- You can put a little bit of Aquarium salt in to help with minerals, fish that are in mineral rich water keep their minerals in, those in mineral poor water tend to leach their own minerals and loose condition and run down their immune systems.
- Shell grit - also handy
- Indian Almond Leaves - have a read about those on this forum and online - I swear by them.
While you're just over in the Vale - next time you're mobile, you might consider going into Subscape Aquarium, one of their services are (and maybe, free? I can't remember....?)
Say Ness sent you and they might do it for nothin'
" We offer a comprehensive water analysis service that will help take the mystery out of water issues you might be having.
Bring in just 100ml of water and we will test for Nitrites, PH, Ammonia, GH & KH."
They also have some nice Halfmoons, CT, Veil tails and Plakats (some Aussie bred too!)
Hmmm... what else?
I don't cycle my betta tanks.... I just chuck in Decholinator and hardness powder, and a few of the extras like IAL/Salt/Grit and they're good to go.
Anyhoo - i'm rambling... nice to meetcha.
Get a photobucket account and take LOTS OF PICS... we might even be able to help with diagnosing what's going on with them fins - sounds like rot or melt - might not be.
