Hi matpreec
If you don't want to use chemicals such as PH minus or whatever, you could try adding various other things. eg. bog wood, oak leaves, clean rain water if it's not polluted or contaminated.
Hope this helps

Hi Paul
You should try Trimar at http://www.tropicalfish.org.uk for your Torpedoes, I'm sure I seen them there the last time I looked.
Cheers....William....

Thanks for the help guys. So we believe I've got C Sodalis. Is this a more rarer and sought after fish or is it becoming more easier available these days as this is the first time I have came across them. And the age old question, are they easy to keep and breed.
Thanks again....William....

Thanks for the thoughts guys. Whatever they are I think they are two cracking looking fish anyway. Pity about being two different species though because they are a pair. Oh well, that's the joys of trusting the weekend help at the fish shop and me just being excited at seeing two good sized, good ...

Can anyone help here ? I bought these Corys as C. Reticulatus, but any pics. I have seen of them have a black blotch on the dorsal. Looking at the Aqualog of All Corydoras they look more like C. Sodalis. Are they just a varient of C. Reticulatus or something different?
Thanks in advance.... William ...

Can anyone please help me to ID these 2 Corys. They were bought as a pair of C. Blochi, but as you can see they are 2 different fish.
