    does anyone know what a good filter is for a 24l tank? I have one currently but worried the flow is too powerful for the fish - any help appreciated!

    I have a fluval U1 in my 30l. What fish do you have in your 24l?

    I know this isn't what you have come here to ask but I`m afraid your 24l is far to small for either an oranda or a moor! Are you intending to move them to a larger tank soon?

    I will tag @magpie for you as she owns fancy goldfish so will be able to give you good advice. Orandas and Moors can grow huge and very quickly so need plenty of space. Unfortunately some pet shops and aquatic centres give terrible advice and will sell anything however unsuitable! 24l is one the small side for anything really but you could (once the cold water fish have been removed obviously) add an heater and have Betta they are beautiful and very friendly.

    Have you carried out a fishless cycle before adding the fish?

    For those two as adults they will need a minimum of 140 litres, though bigger would be better. And as they are such large fish and produce a lot of waste, external filters are better than internals. The filter should be able to turn over the volume of the tank at least 6 times per hour, so a 140 litre tank would ideally need a filter of at least 840 litres per hour.

    While they are still babies you can get away with a smaller tank, but not as small as 24l unfortunately. They will become stunted if they stay in a tank that small for too long, which is very bad for them & can cause health problems. I don't have pics of my fish on my phone but there are a few threads on here with photos of them to show how big goldfish get. My biggest one is around 9 inches long.

    Do you have a liquid test kit to check your water quality?
