tench in a 30gal

[guppy_man]

hi i have a 30gal tank up and ready for coldwater fish i was thinking about having goldfish in there but when i went to the pet store looking for goldfish in the same tank was green tench and golden tench and mirror carp all about 3inches long.

would it be ok to have a tench and 2 carp in my 30gal?
when they get too big i will move them into my new pond which im getting in the summer.

i was thinking of getting a tench and 2 carp from my local canal but then i thought of just buying them, which option do you think i should pick?

I believe it is ileagal to keep native animals in the uk... not sure for definatet though.

But yes they would be too big and WAY too much waste for a 20 gal.

neither!
tench are (large) pond/river fish and as such should be left there
the ones for sale in lfs are,more often than not, farm bred for
people garden ponds.

The Tench can be found in most stillwaters, canals and even rivers and can manage to survive in poorly oxygenated conditions where other fish would not. It is a bottom dwelling fish feeding on crustaceans, larvae and bloodworms and is generally found in small shoals. A feeding fish often releases a stream of tiny bubbles that can be seen on the surface. The Tench is a sturdily built fish with small scales embedded in it's olive green body. It's eyes are small and it has two barbules, one either side of it's mouth. The female of the species has larger ventral fins to that of the male. Colour variations of the Tench can often be found in ponds, usually gold in colour and with a variety of markings, where they have been stocked for ornamental purposes.
A 15lb Tench was caught by Darren Ward from an undisclosed Southern stillwater, falling to a 14mm pop-up boilie whilst fishing for Carp in a pre-baited swim beating the previous record of 14lb 7oz caught by Gordon Beavan in 1993

in short a very big fish!
