    Hey Lizzie don’t worry about your corys – the majority of shop-sold ones have been farmed so in terms of genetics aren’t of great stock anyway. With wild fishes you have to be more careful. Different types of cory will school together so your ‘odd ones out’ should also be fine.

    Thanks so much, Matt. That’s such a relief, I didn’t want to miss them anyway.

    This is a drawing picture of how my tank looks at this moment.

    Hi Lizzie,

    I wouldn´t worry about inbreeding to much. As long as you breed the specimens that look healthy. A friend of mine has been keeping and breeding fish for some 30 years and he has been breeding on a single line (from a single pair) for several years without any apparent ill effects. Though it might be wise to bring in some fresh blood now and again if trying to keep a healthy stock.

    30 years of one line, impressive! I hope my pair of Pepper corys can match up to that too. They’re the only fish that actually reproduce besides of the Red cherry shrimps in my tank. I have an Aeneus cory bronze and one Aeneus cory albino, they have had ( a lot of) eggs, but no off spring so far. I also have one Cory panda (last in the tank at my pet shop) which is about the same age of the Pepper youngsters, they intermingle but I wonder if they will ever pair up. Is that even possible?

    The panda corydora won’t breed with either of the other two as they are of different species.

    Although it isn’t really a huge issue, it is best to avoid inbreeding when and where possible. To continue breeding down a line is only recommended if you are doing so for a recognisable feature, i.e. long fins, otherwise you run the risk of genetic mutations leading to undesirable characteristics, most especially bent spines and crooked fin rays.

    To avoid line breeding, simply remove the young of one sex, take them into your dealer/freshwater-and-brackish-water-fishes society and swap them for others of the same sex. With most fish, this is a really simple process.

    Meantime, just the fact that your corys bred means you are doing something right. Congratulations!

    Albino and regular colour Corydoras aeneus will breed (assuming you have at least one of each sex), and the fry should be normal coloured if the parent’s are “pure”.

    It is not entirely unusual, however, that Cory females lay eggs without a male at all.

    Most corys do not cross breed with other species, but there have been records of some species crossing (making hybrids). It is much less likely to happen if the corys are kept in a group of at least 6 of the same species.

    I had some paleatus cross with a large aeneus female. The spawn hatched, but most were malformed and all died within a month.
