How many Corydoras Aeneus in 26g as only fish?

    I'm thinking in advance now, because if the babies that I have right now survive I would like to keep as many as possible.

    Right now I have a schoal of 8 adult bronze Corys in my 26g, could I keep 8 more? AQAdvisor says with my filtration I could keep 20, but seeing the size of the tank I think that is stretching it a bit...

    Can those of you who keep only Corys' tanks tell me a bit about your set-ups?

    Many many thanks!

    What are the dimensions of the tank?
    Aenus corys get a good 3" so footprint is important for them

    Well, it "seems to be" 32''14''15'', but then the Quick Calculator gives me a size of 29 US Gallons:confused: and I am quite sure it's only 26g

    US gallons are smaller than imperial, I make it 24 imperial gallons or 110 litres.
    I'd only keep around 12 aenus in that size tank.

    Perfect, thanks a lot for that:) I really thought that thank was waaaay too small to keep so many of them, you have to AQAdvisor with a pinch of salt.

    I agree with Coradee, 12.

    Some species of corys are found in blackwater habitats where the water is stained from fallen leaves & vegetation.
    Leaves can be beneficial in a breeding tank as the fry use them as hiding places & feed on the insuforia they produce, I use oak & beech in mine

    Thanks explaining Coradee.
    Cause my oakleaves run out I bought 100 Catappaleaves. They're staining the water more than earlier ones. I love the leaves and stained water !!!
    In autumn I'll collect a lot more oak and beechleaves than past year.

    You might find they need some dither fish above them to feel safe. I wouldn't keep them as the only fish.
     
  12. ReyesValued MemberMember

    Really?? Mine don't even shoal anymore and apparently they only do that if they feel very safe. My tank is a disorganised mess of flying fish;)

    I don't understand your point here... :)
     
  14. ReyesValued MemberMember

    Sorry ;) I meant that my Corys must be feeling very safe in the tank as they don't swim together at all, it's as if they were from different species all together. Only sometimes do their swim in pairs or in trios, but that's all.

    My plan was to get some Harlequin Rasboras, but I would love to keep as many babies as I can, so I need to decide what I want most: baby Corys or another type of fish in my tank

    They don't school all the time, but they still need the company of conspecifics :)

    Mine don't school every minute, but they like to travel in groups most of the time, be it in pairs, trios, or quartets. They usually all "sleep" together though.

    Yeah they'll probably "relax" more than they would naturally once they know they're safe, but when you first get them and put them in an otherwise empty tank... here most fish will be nervous, because the way they see it is that all the other fish are in hiding.... so there must be something dangerous nearby... They might not settle in this situation... but they might.

    :)

    I see what you mean... Thanks for the tip! I will keep the 8 that I have now and include the Rasboras as soon as the fry are big enough to be adopted.
