Strong Currents!

[contrarymary]

hi all...I have set up a 110litre tank for 3 comet goldfish. I LOVE it! Im so suprised how much. The fish look stunning, I had never noticed how long and lovely their tails were in their tiny little tank.

They appear to enjoy their new tank too! They are chasing each other around, and spend along time sucking up and spitting out the sand and gravel!

Im a LITTLE bit worried about the current I have created in the tank. I have put in a Fluval 4 filter as I read (on here i think) that goldfish are quite mucky and eat and poo alot, so I over sized the filter. Have I gone too far??? They have stuff to hide behind. They hang out around the filter intake quite a bit! Is this to avoid the outflow?!

Can you take a video and what are the aquarium dimensions? I can't imagine it being much of a problem.

Edit: it would also be useful if you could tell us the estimates lph of the filter.

Can't you reduce the flow?

Comet goldfish should be in ponds not tanks, they grow huge. someone on here has an amazing picture of a comet in a tank next to a goldie the size of ones you get in shops.

110 litres isnt big enough for one comet let alone three.

i couldnt see anywhere on the filter to reduce the flow

tank dimensions are 80cm x45cmx 30cm

arent at home to take a video right now

Ill try and find some filter information....

its like this;

hanny...yes I discovered that on here a short while ago. My mum gave them, as babies, to my children (from her pond). We cant get them back to pond until after this winter. So 100litres will have to do them for now Im afraid

http/www.hagen.com/uk/aquatic/manuals/fluvic05.cfm lists it as 1000 lph (litres per hour), which is on the high side for a tank of that length, but the goldfish should be able to cope with it. You can stuff some extra filter wool into the filter to reduce flow, specifically between the rectangular and cylindrical containers.

thanks kitty- ill do that
but the fish are ok with high flows?

This one?

Sorry for the bad news, OP. At least it's bigger than they had before and should tide them over until you can ge them back out to the pond; just remember to do plenty of water changes so they don't get stunted; at least 50% a week, twice a week if you can.

I wouldn't worry about the flow; goldies are pretty strong swimmers.

If you really, really think they're unhappy, you can turn the filter so the outflow is aimed against the back glass

If the filter is a U4 as opposed to a 4+, it will have a little knob on the top of the filterbox that you can turn to adjust the outward flow. It can be changed for top, bottom, or a middle spraybar effect, albeit and underwater spray bar. Try the middle setting if you have the U4.

WOW!

thanks Ben- Ill have a look. I bought it second hand and it came with no box or instructions - so I dont know much about it

(haha...can you tell I am winging it??! )

 

[fluttermoth]

WOW!

I know! mental, isn't it?!

It's a pic I use to demonstrate to people why they can't keep a goldfish in a small tank, especially when they say, "but it's tiny"; well, it's not going to be tiny for long!
