    Hi Jim,

    it’s in the Alsace near Strasbourgh. I guess that all pictures of a recently abandoned i.e. dead lake were taken somewhere else since the lake in question had been forgotten about for roughly 20 years. But all other footage is from that lake!

    They were in a 57 litre (60x30x30 cm) tank. The Darios did spawn regularly but were quick to eat their own eggs. From the Elassomas I had about 20 fry within one year, which did grow up in that tank without any intervention.

    I never saw any “real” competition between the two spacies. The males would show off every once in a blue moon but no physical contact ever. As far as feeding is concerned, the Darios were always the first at the food. The advantage is, that (in my experience) both species do not have the tendecy to stuff themselves to the point of bursting, so there was always enough for all of them. The only downfall is, that with both of them you needn’t bother trying anything else but live food.

    Yeah Tom, that would actually be a dream of a tank! :-D

    I have not kept the species you mention yet, just as another option, my best experience so far was with D. dario and Elassoma evergladei.

    So if distribution is not a problem it certainly is worth a try.

    Hi finka,

    for a single Betta, these tanks are not bad at all, certainly a huge step forward from a 5 Litre bowl! ;-)

    Personally I’d always go for glass over acrylic. If nothing else, they’re at least a bit more scratch resistant.

    50 Watts heater is absolutely sufficiant. Make sure it’s adjustable i.e. a heater stat and if it does have a guard, all the better.

    For a single Betta male in a tank that size I wouldn’t even bother with a filter. A 30% water change  every other week will do just fine.

    As far as plants are concerned, I’d go for some suface vegetation and one broad leaved plant e.g. Echinodorus bleheri or perhaps a broad leaved java fern.

    For the bottom you can use either sand or gravel or play around with a mix of both. No need to worry about caves and arches as long as you put plants in there, that’s all he needs to hide and rest. If you like, you can add a nice piece of driftwood or similar but that’s just cosmetics.

    Food: A good variety is important. I’d suggest live food  at the very least once a week, preferably more. Then you can top up with frozen mosquito larvae and such and a good quality dry food such as flakes or granules. Be careful not to feed too much, as they are prone to fatten up quite quickly.

    Hope that was of help to you.

    Regards,

    R.

    Yeah, for 8 of them you’ll need an olympic pool very soon! Frown

    Btw, I do find it quite amazing how all replies focus on the “whatever” fry! ;-)

    I’m quite sure, if I had managed to get a shot on the Pangio offspring, I’d have a response on those too??? :-D

    Jupp, that makes two of us Matt!!! :-D But isn’t it almost too much to hope for?? ;-)

     

    Any particular reason you and Matt are hoping they’re Danio auropurpureus? Aren’t they supposed to be quite easy to breed?

    I don’t really know how easy or difficult they’re supposed to breed but I do know that I’ve been trying for about three years to get my hands on a couple of specimens before I actually did get 8 and that was the entire stock. Haven’t seen any more since!

    So, that’s why I’m hoping they are D. auropurpureus and I dare a guess that it’s the same reason with Matt.

    I don’t really believe in the peacock either but out of the rest it would have the best “outsider chance”. Then again, looking at the tail,………. rather not!

    Not too much that would qualify Matt.

    D. choprae

    D. pathirana

    D. auropurpureus

    and perhaps T. ocellicauda?

    No, I haven’t moved anything in, only out! :-)

    I’m planing on leaving them in there until they’re ready for at least small Daphnia, as the puddle is still full of life. Don’t seem to be malnourished those little buggers.

    Yeah Tom,

    I am leaning towards D. choprae myself. From what I read, they’re fairly slow growing too?

    Hi there Helene,

    it’s me again! :-D

    In my opinion, you are on the right trail of thought! As I did mention in my first reply, keeping large gold fish and koi in a “tank” like that is, apart from the mess, cruel.

    Upping pump capacity without increasing filter surface is counter productive, as flow rate will get too high to grant proper biological filtration. Imho, as long as you have to stick with your current stock, you’ll have to change 1/3 of the water (incl. vacuuming the substrate) at least every fortnight.

    Personally, I’d find a good place for the goldies and kois and get something a bit smaller and compatible with 25 cm water column! ;-)

    It’s difficult to give advice on fish species as I have no clue what you can get. Maybe there are some SF members out there in Norway who can help you out???

    Regards

    R.

    edit: I’m not quite with you on changing the filter mat to 20 ppi!? You say you’ve got a “fine” filter foam in there now. Let’s assume it’s a 40 ppi. If you change that to 20 ppi you’d loose about half the surface which can be colonized by your filter bacteria, hence you’d loose roughly 50% biological filter efficiency. That is certainly not what you want?

    Nice vid Matt! ;-)

    What camera did you use? 

    It rattles like one of those ancient 8mm jobs? :-D

    Hi all,

    had the same yesterday on all browsers and systems! Then I discovered that it happens when I’m NOT logged in! As soon as I log in all is well! Confused
