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



In the home aquarium, the Titanic Plecostomus will readily accept most good quality dried foods such as granules, flakes and sinking pellets. These modern food products have been developed to provide all adequate nutrition to maintain your fish's health and dietary requirements.

Providing additional foodstuffs such as live, frozen, and freeze-dried meals such as bloodworm, daphnia, and tubifex once or twice a week will provide additional benefits to your fish's health and well-being but is not a must for this fish.

It should be noted that bloodworms should only be given as an occasional treat and should not be used as the staple diet as they are difficult for fish to digest and can potentially cause blockages.

This fish is an omnivore in the wild, meaning it will consume some vegetable matter. Although most modern fish foods take this into account and include them in their products, you can still supplement your fish's diet with blanched vegetables such as spinach, broccoli, and zucchini. Ensure you do not overfeed your fish and remove any leftovers the following day.

Sexual Dimorphism

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.
