    Aquariums ...

    Advice please chaps,
    Not Koi but....... My lad messaged me earlier as to how many goldfish he could put in a 50 ltr fish tank, I said none and to take it straight back to PAH.

    Anyway, steered him to buy a 360 ltr second hand tank, I know a lot of variables exist such as filter type, whether he gets ordinary or fancy goldfish ect. I'm hoping to persuade him to use the internal filter and then add an external cannister type as well.

    Sooooo... I'm reckoning he'll be ok with 4 goldfish, does that sound reasonable given growth or is that going to be optimistic?

    4 gold fish would be fine but they will get big one day why not throw in a heater and go tropical loads more choice in fish and colours and the small ones stay small

    Yeah if he’s new to aquarium keeping then it could be best to go for a nice tropical shoal of neon tetras / rummy nose tetras / cherry barbs that are very easy to keep and low waste output. I have a small setup like that with an external filter. I tried to create a nice aquascape in mine but my bristle nose plecos keep churning up the ‘beach’ and ruining the effect Incredibly low maintenance compared to the koi!

    Cheers TAC & Feline, he seems set on goldfish (or it may be his missus) but things could change yet.

    I'm off up to visit next weekend and want to get him set on the right road, I'll mention tropicals and see what he says.

    Show him pics of some of the Bettas for sale- you can keep one of those on its own in a not too big aquarium and they look awesome.

    Bettas are pretty cool I used to have a male Betta in a community tank of neon tetras, cory catfish and guppies. Some said at the time it was ok, others reckoned he'd have the guppies due to their fancy tails.

    Anyway he never caused any bother at all, what really surprised me though was when we put a pregnant guppy in one of those floating hatchery traps, he pretty much sat under the hatchery the whole time the babies were in it. I thought he was weighing em up and would have them when released into the main tank

    What he actually did was herd them up when they were released and guarded them for several days til they were established in the main tank. Amazing behaviour for a fish so they must have very good paternal instincts.

    Anyhow, my lads done the deal on the 360ltr tank, so I'll see which way he wants to go when I visit and try and get him heading in the right direction. At least its someone else's money I'm spending for a change, though thinking about it xmas and his birthday are both coming up so I may get caught out yet lol.

    My very recently set up tropical tank. As Feline said, much lower maintenance than koi, although I am now dealing with white spot. Parasites seem to follow me about.

    4 Fancy Goldfish in 360 litres is fine.

    Generally that was my maximum when I kept them, but 2 was my preference as I could go longer between tank cleans (every 10-14 days with 2, every 7 days with 4).

    Filtration wise for that tank I used an Eheim Classic running 1000 LPH plus an Eheim Professional 3 running 1200 LPH.

    No worries.

    In that volume with good water and plenty of food you will be surprised how big they will grow. You know those tiny blackmoors and telescopic eyes you see for sale at Garden Centres etc, I have got them to a foot long (including Tail) within 3 or 4 years.

    So even with just 2 fish you can end up with 2 foot in total fish length in a 4 foot tank!

    Officially with fancy goldfish though, the tail isn't included in the total measurement unlike with koi.

    These were the last 2 when I sold up, both 18 Months old when photos taken, body length about 4-5" and tail about 4-5" on top. Another 2 years and a total length of 12" would have been quite achievable.

    Bloody hell, monsters , I can see why the cleaning regime needs to be spot on. They look great those RS, would make quite an impressive display with just the two then as you say.

    I was gutted I didn't live closer when you were selling them rs would have had them in a heart beat . Instead of all the life wasters you had with them
