Tomorrow I’m buying a few corys, 4 to be exact. Can I mix different species of them or they should all be the same. Lets say I buy 2 albino 1 panda and 1 spotted will that work? I want them to school and interact with each other, I also don’t want any territorial issues (don’t know about this one, after all, they are community fish).
Congrats!! It's a decision you won't regret. What Cories lack in looks, they make up for it in character.
The top 5 popular (and common) cories are:
Corydoras panda
Corydoras Sterbai (and albino variant)
Corydoras Trilineatus
Corydoras Aeneus (and albino variant)
Corydoras paleatus (and albino variant)
Most corydoras are perfect community citizens and will shoal with each other (there are exceptions of course). Those that you've picked out will be fine with each other. There will be no territorial issues amongst themselves. However, most literature recommend a small group of 6 if you can affort the space.
As far as stocking density is concerned, a standard 57 Litres tank (sorry, I always get confused with US Gal and Imp Gal) can hold 8 corydoras (depending of species) comfortably and they will grow to their full size. However, a lot of aquarist (myself included) have a tendency to overstock. As they are community fishes and extremely socialable, a slightly higher density is usually not a problem, provided the water is clean and free of Nitrite and Ammonia.
This will be severely overstocking, but you can clearly see that cories do get along fine even if they are of different species.
Though you didn't mention the other occupants of the tank, I assume that you are not keeping any fishes that will grow too big to harass them. As a standard rule, other fishes in the tank must not have mouth large enough to swallow the cories. Also certain aggressive species (e.g.
Anostomus anostomus) are best avoided as tankmates for corydoras.
Have fun!!!!!!!!!
Cheers,
