Why is my fish eating all my other fish? (continued)

Thank you for your answer about my fish, you said do not get fish that are smaller than him. I’ve bought fish that are bigger than him and he still attacks them and eats them!

Answer #1

Either you have a very aggressive and territorial Black Moor or it’s another type of fish. Are you sure he isn’t a Tiger Oscar?

Answer #2

Hi jody,

I just did some research on Black Moors for you, and found out a few things about them. They are known to be the most gentle goldfish, According to centralpets.com,

The Black Moor is a peaceful fish. It usually mixes very well with other goldfish. If kept in groups of goldfish, the Black Moor will school with them. These fish do well in many community tanks, but should not be housed with aggressive fish,

So my questions:

  1. Are they in a tank with other goldfish or a variety of fish? Maybe just goldfish would be ideal.
  2. Are you sure it’s a black moor? The behavior you are describing is very uncharacteristic of the type of fish.

Here’s a picture of a black moor.

Answer #3

I just caught my black moor eating my fantail fish lol I had 3 fantails, now I’m down to 1. Wasn’t sure which fish it was but I busted the black moor chomping the fantail down to size. So …. so much for being the most gentle goldfish. The cannablism was upsetting the children so I netted up the torso and head of the fantail and we buried it at sea. I have one fantail left. I’m giving him til the end of the weekend to survive. In the meantime, all eyes are on the Black Moor.

PS. Darn, I should have videotaped it and attached it lol BUSTED!
