Answer 1

The fish you are referring to is a Black Moor Goldfish. It should get along with other goldfish of similar size. If your exist goldfish was smaller than this guy, that might be the problem.

The more likely problem is tank size. How big is your tank? If the goldfish are too cramped, they can get aggressive. They need their space. For 2 goldfish you really need at least a 20 gallon tank (10 gallons per goldfish).

I once kept 2 small goldfish in a ten gallon, but I was doing 50% water changes twice a week to keep the nitrates in control. They got along fine in there. But once when i was moving i put them into a 2.5 gallon tank i had for a short period of time and one starting chasing the other.

If you want them to stop fighting, seperate them or get them a bigger tank. I know 20 gallons might seem like too big for 2 little goldfish, but if you treat them right they will be much happier and won't be little for long.

There are some fish that cannot be put together... though I was under the impression that those Black ones with bulgeing eyes are in fact a type of goldfish.. i've never seen them fight before, in fact in some shops they keep them together. Are they very different sizes? If the goldfish is a lot smaller maybe he is being picked on because of that... I think the best is to just get them seperate tanks.. I can't really see any other option I'm afraid

Hi Thumbs Up, As a general rule Goldfish are very picky about their tank mates. Only similar sized, similar types of Goldfish should be housed together so keeping fat bodied fancy types with streamlined non fancies is not recommended. Likewise keeping a big fish with a little fish is also asking for trouble.You don't say what type or size your other Goldfish is but even if it is a fat bodied fancy & a similar size to your Moor there may be other factors such as size of tank making territorial issues emerge.

If your tank is less than 20 gallons I suggest either upgrading to a larger tank where they both have more room or taking this new fish back to the shop-otherwise your problems will most likely only get worse & this is unfair to your current Goldfish.

Regarding the damage to his tail I suggest adding a mild salt solution to your tank for a couple of weeks- you can use rock, kosher, sea or aquarium salt but never use regular table salt as it has harmful additives. Check the green table on the link below for dosage instructions-I would go with just over 0.3%. Of course you must resolve the situation between your fish before you start medicating & if you have any remove live plants to a holding bucket as the salt will kill them.

They are compatable you have a black moor goldfish. One is male (chaser) and one is female (chasee). Or you don't have enough room and the moor is picking on the other one. Goldfish need 10 gallons of water per fish.These two should be in a 20 gallon tank. They could be working out pecking order. I have heard that moors can be a little aggressive. Separate if you can. The one being picked on could be sick which can trigger aggression in other fish. The new fish could have brought something in the established fish is not immune to.
Bleeding fins could also be a sign of high ammonia and not necessarily due to fin nipping.

Answer 5

you do no longer say what proportion or what forms of fish you had. it would desire to be rather considerable to nicely known which you will have no presented 'unwell fish'. it could have been an elementary case of overstocking the tank (that's rather elementary to do for novices unknowingly with 10 gallons) and whilst a tank is overstocked the bio load won't be able to shop up and all the fish finally end up unwell and ineffective. If it have been me i does no longer prefer to tear the tank aside and sparkling on account which you may ruin any good bio load you probably did outfitted up interior the cycling technique. i could do a 50% water exchange, sparkling the gravel with your syphon such as you may routinely do with maintenance, and dose with Seachem's top. it is the excellent conditioner on the industry. enable the tank run on that's very own for awhile, no fish. in case you had tropicals and had a heater, turn it as much as 80 two, 80 4, this could kill any leftover parasites and that they are going to die without fish to host them besides. ensure you are trying out with a drop kit, ammonia & nitrites could be 0 flat, and nitrates below 20 ppm. as quickly because it is the case you may introduce fish, slowly. yet be helpful to no longer overstock! this could reason the perpetual ailment and death you have defined. For 10 gallons, 5-6 neon tetras could be ok. Or, 2-3 platies. Even a crown tail betta with ac ouple of african dwarf frogs or ghost shrimp could be intense-high quality. various human beings recover from excited and attempt to p.c.. fish in there and regrettably 10 gallons merely isn't a lot to artwork with and it inflicting the bio load to crash. good success : )

Answer 6

You have a Black Moor and in reality he should be fine with your goldfish! I can't imagine why you are seeing blood on your fishes fin as there is nothing there to bleed! **

Answer 7

Here's a clue, if you ask someone that sells fish,if you can put the new fish in your tank they will always say "yes". They sell fish---duh!

Answer 8

put in a seperate tank
