i do a 20% water change once every 1 and a half 2 weeks..
but i was thinking 2 large discus would look great with heeps of cardinals and rummy's thats why i am getting rid of the 3 smaller ones.
i usually see a pair of discuss alone so im pretty sure it would be OK ? correct
I think the fact he only lost 1 discus of presumably 5 over an 8 month period was most likely why many people did not suggest to touch them (relocate etc.). Obviously he was doing something right.
It's a shame you got rid of the 3 smaller ones, let's hope you didn't upset the balance and proceed to lose all your luck.
