I just want to help make sure nobody does what i did to my oranda and fantail.
I bought a glass cleaning magnet that has a connecting cotton between the two halfs.
My bad mistake with this was to leave the magnet in the tank when i had finished with it.
My oranda and fantail both got caught in the cotton ( i think overnight ) and now have bad cuts to their fins ( which thankfully are healing well ).
My oranda has a cut dorsal fin which bends in half now
and my fantail has a white circular cut around the base of her fantail.
I never let the cotton drift about in the tank but fish actions may have pulled spare cotton in, enabling enough cotton to get entangled in.
Also magnet was left at rear of tank behind plants so i might not have seen the entanglement sooner.
In short fish buds take your magnet out it isnt worth the risk.
