Re: Inherited fantail poorly and in need of a bigger tank
Thanks for your reply. Is it absolutely necessary to get a 151-250L tank though? I know the primary aim is to have a happy, healthy fish but I really haven't got the room, money, time or energy for a tank that size.
Take a look at https://www.completeaquatics.co.uk/aqu ... uarium-tanks-and-cabinets and, on the LHS, you can choose aquariums by size - start with the 151-250L but also take a look at the larger ones, and you might see a brand and size that "fits the bill". An interim measure is the 145L Really Useful Box which would certainly be a better sized option than what you have currently.
List of native British fish for large natural pond
I have inherited a large natural pond - something like 40 ft by 300ft. I’m told that it used to be a fishing lake, but there are no fish in it currently. There is a stream into and out of the pond - which is the problem. I turned up to the local aquarium shop to buy half a dozen koi carp, but was told that only native British fish can be kept in a pond that empties into a waterway. What they couldn’t tell me was what a native British fish was. It seems that many fish found in British rivers are not native but naturalised - sometimes several hundred years ago. Also the common form of a fish might be native, but what about the fancy forms that aquariums sell? Ideally I’d like a mix of species but would like some that are brightly coloured and grow large, so there is some chance of actually seeing them. Would golden orfe qualify as a native British fish, or failing that golden rudd? So far I’ve established that I can have sticklebacks and minnows, but that’s not a very inspiring list. By the way the water leaves the pond via two 6” pipes with grids over, which will prevent fish escaping (but not fish eggs).
Inherited fantail poorly and in need of a bigger tank
Hi, I inherited a fantail in a 28L tank from my daughter when she came home from Uni last summer. At the time he was only small and my daughter said he didn’t like the pump as it was too powerful for him. I read a review at the time from someone who said the same thing so as he seemed happy and healthy I left it as it was. Up until now he has seemed fine with a 10L water change every 10-14 days but after the last water change on Tuesday he became rather lethargic and was just sitting at the bottom of the tank. I have a bottle of ammonia remover which my daughter had bought so I put some in the tank, along with the pump, and it appears to have helped as he seems a lot happier.
Since last summer he has probably doubled in size and is now about 4cm long (excluding tail) so I’m guessing he is suffering from poor water quality and needs a bigger tank. I had wondered if a 75L tank would be enough but some articles and comments I’ve read from others posts suggest not. I haven’t got room for anything too big so I guess I’d really like to know what the smallest I could get away with would be whilst also making sure he’s happy?
Also, can you recommend any particular makes/models?
Some years ago I had a weather loach in an Aqua One Aqua Start 75L tank and I really liked the built in trickle filter and lighting. However, from a comment I read on a forum, its successor – the Life Style – has what seems to be a flaw in its design in that the trickle filter either sits in the water or you have to have the water level below the top of the tank so I’m wondering if any other makes do a tank with a built in trickle filter that might be a good alternative? Given that we’re currently not allowed out and several shops are shut anyway, I’m probably not going to be able to get a bigger tank for a while. What would you suggest in the meantime? Will he be OK in the 28L tank if I do bigger/more frequent water changes? I plan to at least order a water testing kit for now so I can keep an eye on the water quality. I’m kicking myself for not getting one before and that I’d not got him a bigger tank with filter and such like when I inherited him. It’s such a stupid thing to have done as I told my daughter when she bought it that it wouldn’t be big enough. I just hope fishy will be OK.
You're really looking at a bigger tank than that for an oscar - 5ft x 2ft minimum, so I would stick to something a little smaller. Green terrors are extremely aggressive and shouldn't be mixed with other fish (except as a mated pair) in less than about 650 litres. Silver dollars need at least 6ft in length.
