About two years ago I bought two Metae (Bandit) Corydoras for my 26 gallon tank. I quickly found out that they need to be in groups of 6+. When there were just the two of them they hid in the back of the tank constantly and I rarely saw them. I assumed it was because they needed more friends to feel social and safe to explore more. I recently upgraded to a 55 gallon tank and have 12 Metaes now. The tank contains driftwood and plenty of plant cover, but their behaviour hasn't changed at all - they still hide all the time. It's a bummer having fish that I can't enjoy. Is this just their personality? Is there anything I can do to encourage them to explore more? At this point it's just them and some Otocinclus in the tank. In the coming weeks I'll be adding a shoal of tetras and several Hone Gourami. Will that help the situation at all? If it's just that this species is particularly shy, are there other Corys that are more outgoing?
