Thread: Golden tench

    Golden tench

    Anyone have any tench in the pond and any issues that come with it? Since ramping up the feeding and stupidly not putting enough returns in opposite end for flow Iím getting a lot of waste settling on the bottom after a few weeks. Been reading tench can be a good hardy fish to keep the bottom nice and clean.

    If you’re thinking of introducing a fish (other than koi) to a pond a tench would be my first choice,
    l’m not sure about how good they are at keeping the bottom of a pond clean, but they don’t call them doctor fish for nothing

    Freddyboy had them . The slime coat is meant to be good for other fish (not sure if it could also be a mare when needing to treat ? Ie parasites hiding under the extra slime needing more pp to help remove)

    Can one of the air bars not be added as DTF has ? As my understanding is no fish will clean the bottom it's just all about the movement

    I've got a couple of tench in with my koi and they've been fine with all the treatments I've put in the pond.

    I think they are hardier than the koi and don't seem to react adversely to any of the treatments I've thrown in so far - which has been PP, salt, acriflavine, alaprex, chloramine T, various different Kusuri fluke treatments and an overdose of lernex pro.

    The only issue I found is you can't really do a scrape on them, which surprised me as they feel so slippery you'd think they'd be easier to a do a scrape on than koi. I attempted it a few times and didn't get any off and just some black pigmentation, so I've not tried since as I don't want to hurt them.

    They are bottom feeders but they won't keep your pond floor clean. If anything they'll add to the waste.

    As AJM said no fish will keep a pond clean., other than maybe the movement of a big fish kicking debris up into suspension or towards a bottom drain.

    Cheers guys, Iíd love to get some variety in the pond, tench sounds like a good choice. I have noticed since turning the air up on the bd for summer things seem a bit more cleaner on the bottom!

    I had 3 big golden tench 45-60cm before - I got them coz I couldnít keep koi alive for one season they all died of parasites of bacteria. I almost gave up on koi so got golden tench instead. They are bullet proof fish no treatment upset them more than koi.

    They grow very slowly and itís hard to get them in that good nature size.

    2 years later I managed to keep all my koi alive and well and guess what with some koi getting big and my Ďtasteí getting more expensive - I had to move on those lovely tench. They were sold separately to other new ponders and Iím sure theyíre happy as Larry.

    They will NOT eat koi poop - thatís a myth. They prefer to root through substrate which is what harbour bugs ans bacteria. They love plants too. I had to get rid of plants due to bugs hiding in them.

    I now have a sterile pond with no rocks pebbles plants and with just koi - probably why the chap sold me these three large golden tench for less than £100 in the first place

    When water gets to sub 15 they wonít surface feed - they do need a bit of food now and then. So you may need to get some sinking pellets or sturgeon food. They donít compete very well with koi for food so feed the floaters first like how youíd feed sturgeon

    I've had a golden tench in my pond from the start. It's been through every single pond treatment you could imagine, at much higher than the packet doses

    ...well that jinxed it. The footlong tench managed to make it into my bottom drain and it was dead in the drum today! Shame. Can't even see if there's and issue with the BD lid as pond is green as UV has been off during treatments.

    I've got green and golden tench in my pond and they have been no issue. Been moved about 4 times. They are a bit skittish but they will happily eat from the surface at the same temperature Koi will. They just come straight up from underneath the food, grab a pellet or 2 then shoot off. A few minutes later they come back again and do the same. I've even seen 2 or 3 of the bigger Koi fighting over food and a Tench pops up and steals it from them. As others have said they are slow growers but I think the green ones grew quicker than the golden ones. They are really quick which makes them hard to catch should you need to at any time. I did find they were quite expensive for their size compared to similar sized Ghost Koi.

    That's so true about how they feed.

    I didn't really expect them to feed off the surface but they do.

    They are pretty stealthy. I rarely see them when they are at the surface (I only have green tench). The only way I know they have fed is I hear a small splash and I look round and the pellets that were there are gone.

    My green tench just appear out of the darkness right under the food then grab and go but although the golden tench do the same they will also come up with the Koi once they feel brave enough.

    In the first pond the tench wouldn't get a look in at feeding time so we tried them on sinking starlet food which worked for a while until the koi got a taste for them.
