Name: Corydoras caudimaculatus
Origin: Guaporé River Basin
Rare in the current UK aquatic stores and thus commanding a higher price than your average cory, these attractive little guys are well worth the price tag. As with all cories, they prefer to be kept in shoals of 4 or above, the more the merrier. Caudimaculatus are said to prefer the higher end of the temperature range, and are extremely sensitive to water quality. Regular water changes and low nitrates are essential, and soft acidic water is preferred. Not advisable for beginners, as these guys are not as hardy as some varieties and are said to be hard to breed - but I will keep trying! My group of 9 Caudimaculatus do not seem as bold as the cories in my other tanks - they scuttle away when the glass is approached, but are always out and about in the tank. They appreciate a well-planted tank with plenty of hiding spaces. Feeding is as for all cories - they love sinking catfish pellets and bloodworm.
A word of caution when buying ANY corydoras - a lot of these fish are barbarically injected with dye - look out for albino cories sold as 'Blue Tail-Spot' or 'Red Tail-Spot' cories. I have seen Caudimaculatus which have had purple dye injected into their black tail spot - the black is natural - purple most certainly isn't! They were labelled 'Painted Tail-Spot' cories. Please always research any fish before buying to avoid purchasing dyed fish.
When two of our three Bolivian rams paired strongly they began attacking the third, a female, so we moved her to a small tank with cardinal tetras and 6 tail spot corys. They all (tetras, ram, corys) hid in the back until we introduced two blue rams. Over time the bolivian ram has come to the front, and so have the tailspot corys who she seems to have adopted. They cluster in a group of 6 in the front corner of the tank and she sits over the top of them, fanning them the way the pair in the big tank do with their fry. The tailspots now move around well with her to protect them (especially from the blue rams who always try to steal their wafers), and she has her colours back.
