Me during an interview were we moved the Shampupa Royal Pleco's (Panaque titan) also known as L418 in to our exhibit aquariums after their quarantine. We keep new fish in quarantine for 1 month before the enter our exhibit. 


Paraguay Pleco (Hypostomus latifrons) is also known as L051 and L281. It grows to around 30 cm and is native to Río Aguaray-guazú, Río Paraguay basin, River Paraná system.

Part of the planted tank which totally contains more than 10.000 Liters of water.

The Pleco species is an undescribed Hypostomus species. It came as a bicatch from Paraguay.

The mouth of the Snow King Pleco (Pterygoplichthys ambrosettii) This species was formely known as Glyptoperichthys anisitsi and Liposarcus anisitsi.  

The Red Fin Cactus Pleco (Pseudacanthicus pitanga) also known as L024 grows to around 50 cm TL.

Tail of the Red Fin Cactus Pleco (Pseudacanthicus pitanga) also known as L024.

During the Danish summer our rainforest plants grows out of the exhibit and we have to cut the branches so that the automatic windows can close. We use the branches to decorate our aquariums. The idea is that nothing goes to waste.

The Snowball Pleco (Baryancistrus sp.) known as L142 and LDA033 have bred at Den Blå Planet Aquarium in exhibit no. 23 several times. First time was back in 2016 and we managed to catch some for our smaller display tanks. This species have to my knowledge never been bred in captivity up to that date. The parents were around 30-35 cm TL. The fish in the photo is from the first litter.

This is part of the more than 90.000 liter exhibit no. 23 which also house stingrays, arapaima, redtail catfish and many other species.

This is the Colombian Blue Eyed Pleco (Panaque cf. cochliodon). Some scientist believe that these specimens from the upper Rio Magdalena is a different and undescribed species.

All our aquariums have tablet and you can download the app free. You can choose between English, Swedish and Danish language in the app. The aquarium also have free WiFi called AquariumGuest. 

The Pig-nosed turtle (Carettochelys insculpta) also called Fly River turtle likes to stay near the overflow as food items might pass by. They also like to squeeze in to tight places to scratch their shell. It almost looks like the are stuck.
