With rust red spots all over, this is a very nice Ancistrus species nicknamed after its river of origin. It was never given an L-number but has managed to gain foothold within the hobby due to its willingness to reproduce in captivity. With its great looks, small size and modest demands, it’s got all that’s needed to become a very popular catfish among aquarists.
Facts:
Name: Ancistrus sp. “Rio Paraguay”
Trade names: Redspot Bristlenose, Rio Paraguay Ancistrus
Origin: Rio Paraguay, Paraguay, Bolivia
Maximum TL: 12 cm / 5”
Fish exports from Paraguay and Bolivia aren’t very common, so new wild stock of this species will not occur regularly. But since it’s easy to breed and low on demands, it’s spreading quite fast within the hobby. Its basic needs are easy to fulfil if you are a responsible fishkeeper with normal, well maintained set ups. It will eat anything, including algae, and has no specific demands when it comes to water parameters – if it’s clean, well filtered and within a normal tropical temperature range. They are big enough to reproduce already at 5 cm / 2”.
