Titanic Plecostomus (Pseudacanthicus sp.)

The Red Titanic Pleco is one of the most colourful and impressive species of Plecos that will bring wonder and joy to any aquarist that can house them. These Plecos are somewhat peaceful, providing they have enough space. If they are housed in an aquarium that is too small and feels cramped, they can become pretty aggressive towards their own kind and other bottom dwellers or Plecos, so do not house them together. Despite their defensive protection, they can be bullied by faster-moving fish of similar size. The best tankmates for these fish would be large Catfish, South American Cichlids and Larger Tetras.

The Red Titanic Pleco requires a huge aquarium that is at least 450 litres. The water quality should be pristine; therefore, a sound filtration system, lots of oxygenation and regular water changes are required. You must also provide suitable caves and territorial boundaries using things like driftwood, rocks or artificial caves, alongside plenty of cover from plants as these fish are rather secretive. These Plecos also prefer dim lighting.

Red Titanic Plecos are not an actual sucker mouth; instead, they have a more suitable mouth for grasping and holding food items. They do not have many teeth; however, they are powerful and significant, making them ideal for cracking open small crustaceans and snails as well as grinding meat. In addition, these Plecos have rich colour patterns of reddish-gold and a unique, almost metallic sheen displayed on the back half of their body, as well as their lyretail.

There is a colour variant of the Red Titanic Pleco known as the Yellow Titanic Pleco.

Natural Habitat

Red Titanic Plecos are endemic to Rio Tapajós in the Para state of the Lower Amazon in Brazil in South America. They inhabit highly oxygenated, fast-flowing, rocky, clear waters with a sandy substrate where they usually remain in rock crevices or caves throughout the day.


What to feed the Titanic Plecostomus

Red Titanic Plecos are omnivorous that initially require a meat-based diet such as prawns and chopped mussels, which appear as a favourite and promotes desirable growth. However, once they are settled into your aquarium, you should also provide them with vitamin-rich dried foods such as wafers, pellets and sticks, as well as vegetables like cucumber, zucchini, eggplant, and potato to balance the diet.

How to sex the Titanic Plecostomus

It is somewhat straightforward to differentiate between female and male Red Titanic Plecos. Males will have broader heads have slightly more prominent pectoral fin rays, and they appear to display a brighter, more cosmetically attractive patterning. In contrast, females are duller and have fatter bellies even from an early age.

How to breed the Titanic Plecostomus

Unfortunately, there are no reports or records on the successful breeding of these fish. However, these fish are most definitely cave spawners.
