Hello,Danny........
first of all :
You will not get ornatipinnis if you order them!!!
I know 2 cases,one in the UK and one in Germany,were Ch. ornatipinnis were ordered and pulchra were delivered!!
There is one guy ,from Singapore,who I Think ,has no clou of Channas,he is selling bigger pulchras as ornatipinnis!
So watch out........
Only pulchras are available!
For caring pulchras:
They come from a small hill stream in the Rakhine state of Myanmar!
They need cooler water,because in hottest period of the year the water temperature is not going higher than 25°C!
You need a very well structured tank,with a lot of cobble stones where they can hide!!!!
If they see each other they attack!!!
most Important:
A very big pump for circulation!!!
I keep several pulchras in a tank of about 120 Litres (95 cm length x 50 cm deep x 30 cm high)
I have installed a pump (Tunze Turbelle)that makes 6000 (six thousand!!!!!) litres per hour!!!
They like it........and they are calm now!
About bankanensis:
Here in Germany it is no problem to buy them!
For mysel I have got 2 different varieties of Ch. bankanensis at home...........
One varitiy is about 30cm and the other grows not bigger than 20cm maximum size!
I have breed them ,too.........
What you need is very soft and acidic water (PH 5-6) to make them feel comfortable!
Minimum tank size for bankanensis: 1m in length!
They could be qite agressive to each other.....so you need a well structured tank as well!!!
