Peckoltia sp. L451
It's certainly possible that L451 was exported on several occasions without being labelled correctly. It's typical Peckoltia looks with broad black bands on a lighter background makes it very similar to several other types from the southern Amazon tributaries. Very little information has been published on L451, and even the original publication in DATZ magazine (July, 2010) is very short. In the article, it's claimed that the species has been in the hobby for some time before it was given the number L451, and it was then known as Peckoltia sp. “Santarem”. No accurate location for where it was collected was then known. In a recent (October 2015) import from Brazil, Northern Lights Aquatics was able to include a number of L451 collected in Rio Curua, near Alenquer. It has already been bred by Norwegian hobbyists. L451 is however not on the positive list from IBAMA, but due to it's looks being very close to L15 / Peckoltia vittata, it may be more common than we have realized.
Facts:
Name: Peckoltia sp. “L451”
Trade names: L451, Peckoltia sp. “Santarém”

Compared to L15 and L140, L451 shows a more spotted pattern on the head. Among the original imports, there was an individual with 8 hard rays in the dorsal fin, which is one more than what is known in other Peckoltia types. However, other L451 show the regular number of 7.
Often wild fish needs some proper care and feeding to regain their strength and vitality, and when they are happy and relaxed they will show off a beautiful orange colour in the fins. Stressed individuals are pale with slightly washed out markings. L451 is an omnivore, so a varied diet is required. After a period of maintenance and conditioning the fish should be possible to breed in typical Peckoltia manor. Clean, warm water with good movement and a tank furnished with decent caves and other hiding places makes the fish feel relaxed, and the males will eventually show off some impressive odontodal growth, especially on the upper caudal fin ray.
