    I need some advice, I have had two black Moor fish for 3 years and about 1 month ago one died. My remaining fish seemed very depressed so I purchased 2 small goldfish for company. They seemed to be getting on, however it seems now that the smaller darker gold fish is attacking the larger original black moor fish. The large fish is about 10times the size of the smaller fish. Should I split them up?

    Welcome to the forum

    What tank size are they all housed in? If they were in a suitabley sized tank there shouldnt be a problem.
    My therapist says I need a bigger tank . . . . .

    They are in an 18x10x10 tank.
    Do you think they need a bigger tank? I am a complete novice at keeping fish, but I have become very fond of the ones I have and do not want to cause them any stress.

    Im not sure how many gallons that is, but I know right away its too small for your stock. If you go to the goldfish section in the forum there is a lot of info on minimum tank sizes and requirements. I think a 75g is a starting size for goldfish.

    If my memory is correct common goldfish can easily reach a foot long and moors just under a foot. Really commons are pond fish.

    My math skills aren't the sharpest, but that should be about 7gallons. I'm afraid that's too small for even one goldfish. They get really big, not that you'd know it from seeing them in petstores... I'd advise you to get the biggest tank you can for them. I'd suggest a tank size, but I'm no expert on goldfish sizes.

    I put 3 feeder goldfish in my 55 gallon a few years ago and they grew to almost 8 inches. I had to put them in my mothers pond because they were getting so big!

    So even though they look small in the LFS they do grow quite large so Id consider getting as large of a tank as you can.

    There's your answer on why one is picking on another - there isn't adequate space for any of them to get away from each other and your water quality is probably poor because goldfish produce lots of waste - that stresses out fish as well and they will pick on each other.

    You have had this Moor for 3 years and claim you are a novice? After 3 years of this fish being in this small tank you certainly should have known by now that Moors get 10 inches and need far more room than you have given it...........much less two Moors in that space or one Moor and two unknowns.

    I betcha those "unknowns" are common goldfish that will reach one foot?

    There is no reason for not knowing your tank is too small for ANY goldfish after 3 years. I simply must believe you must be a TROLL because that is the only explanation for this.
