Hi! I have this problem that has been going on for a while now. I have 2 fish. One is a black moor and the other is a whitish/silvery twin-tail (i am not sure exactly which type it is). When i first got the twin-tail, in november, i noticed that he bit both of the fish in the tank (i had this other common goldfish which passed away a couple weeks ago). he chased them around, biting both of them particularly the one that was weaker (the one that passed away). so i took him out and into another tank for around a day, and put him back in. he appeared to have stopped biting. then, a week later, he started biting them again so i took him out again. after just under 2 days i put him back in. he again appeared to have stopped biting. then the common goldfish passed away. just today, i saw him chasing around my very healthy black moor and biting him. he actually chased him around the tank pretty aggressively and biting him. he even bit the black moor's eye, or some place around it, but i think the eye is still okay. the black moor seemed to be pretty stressed out about it so i took the twin-tail out again. i have no idea what to do. help!

Hello Vintagy and welcome.
Before we go any further you should read the two links at the bottom of my signature.
The problem is that you've put fish which need a lot of space in a tiny tank. Single tails need at least 20gallons each and are much faster swimmers than the poor, old, blind telescopes. 10L is just about 2 gallons!
You need a much larger tank and you may need to keep the fish separately.
Post back after you've read up on the links which will provide info on basic fish care. OK?

pixifish is right, Goldfish have very large space requirements, don't fell bad though, we have all made that mistake at one time or the other. the reason for the chasing may be because they are in a confined space. if they get too cramped the get freaked out and start getting a little aggressive. the best thing you could probably do would to get those two fish into a bigger tank asap. twenty gallons at minimum. good luck.

i know i should get a bigger tank but the table i keep my tank on currently cannot fit a big 20 gallon tank on it. a 20 gallon tank is about $120 - 150 CAD. ive already spent around $200 on my fish so atm i cant get another tank. a 10 gallon tank is about $60 - 90 CAD. im giving the biting fish away because the person at the pet store said in that tank, you can only keep one goldfish.

im really low on cash right now =P and parents wont get it for me because they think it takes up too much space.

thanks for the help anyway =PP

i might end up giving coca cola, my black moor, if he gets bigger to someone who has a bigger tank so that he will be taken care of properly. then i may use my tank to keep a betta in.

I'm so sorry that you have to give your fishie away, but I am honored by the fact that you are doing the right thing for the fish. A betta would do very well in your tank. I am sure that anyone would love to have your moor, if you decide to rehome him, as well. I made the same mistake you did as when I first started, I had two gf in a 2.5g tank!!!! I was totally clueless!!! My fantail also pecked at my moor. It took me a while, but I finally got a 29g tank for them. You know, you can always use Rubbermade containers and a filter if you can't afford another tank?

rubbermaid containers?? what kind?

can you show me a picture or something? that would be really helpful =P

thanks!

Hello

For containers, I would think that something like this would work.
I've never used them, so you might want to wait and get an opinion from someone who has.

Good luck with your fish!

Debbie

has anyone here used one of those?

and this is completely off-topic, but i seem to be the youngest one here XD

I use "rubbermaids" (they're honestly just generic plastic containers that I bought at a storage store), they work very well as a substitute for an aquarium. I currently have a large one in use for my snails with some plants and another with just plants until I have my new aquarium set up.

They'll work just fine for your fish! I'm sure they would love the extra space if you decide to keep them. :]

Good luck!

I think the youngest member is 10 or 11 and there are several here your age

Yes that's right - my little girl 'Inkfish' has just turned 11. And Shamu lives in Canada, like you, and is 15.

Did you read the links Vintagy? While you're deciding what to do you it's important to start learning about water quality and water-changing for your fish. In such a small space, it's the only way to keep him healthy. Do you have a test kit for your water?

It was a very good idea to re-home the fast fish, even though you probably felt sad about it. If you can get yourself a bigger crate, just for now, you will be able to care for the Moor - if not, your idea of a betta seems the best idea. A goldfish really cannot live in 2 gallons.
Once you have a little more money you can always save up for a proper gfish tank later on. If you stay around on the board, read all you can and ask questions, you will learn very quickly. People here generally know much more than petstore employees, so always ask here for the best advice.

I hope you stay around the board. Don't forget to read the links.

haha im giving away the fast one tomorrow =P

rubbermaids have no...ummmm..."toxins" or anything bad in the plastic right? and you can just add a filter and put in water and plants and gravel?

nope

Again, I'm hoping someone with more experience can add to this, but I believe that so long as you use the clear/whitish containers, there is no worry about anything leaching from the plastic.
