Hi there,
I have had a calico fantail on it’s own for 6 weeks in a 32 gallon tank. He is vert small.
today I added a ryukin which is about double the size of the fantail. The fantail has been chasing the ryukin non stop since I added him to the tank. The ryukin does not seem stressed but I think the fantail is sometimes nipping.
im not sure why a smaller fish is attacking the bigger one. I turned off the lights and moved some decorations. Nothing is helping.
will this behaviour stop over the coming days?
any advice would be great.
