Aquarium Advice Regular
My two Leporinus' (leporinii?) have suddenly become much darker in colour.
Do fish sometimes get darker in colour if they are under stress or feeling aggressive or mating?
They have been behaving oddly the last few days...swimming side by side and flicking their tails together. And one chases the other around.
Today they seem sluggish and I'm worried. No spots, their fins look fine. Ammonia and Nitrites are zero, Nitrates about 30 to 50.
Any ideas?
Thanks,
Greeny.
