Species of Concern for the Big Fish Campaign

1. Among the species of most concern are:

Iridescent Catfish and all species of Pangasius and Pangasianodon catfish.

Black Pacu - Colossoma macropomum

Red Pacu - Piaractus brachypomus

Red Tailed Catfish - Phractocephalus hemioliopterus

Tiger Shovelnose - Pseudoplatystoma spp.

Hybrids of Red Tailed Catfish with others such as Tiger Shovelnose

We would encourage retailers and wholesalers not to routinely stock the species in the above category 1, and fishkeepers to avoid these fish unless they have the substantial means required to house them long-term.


2. Additional species of concern include:

  • Arowana (mainly the more commonly-sold Silver Arowana)
  • Giant Gourami
  • Cigar Sharks
  • Clown Knifefish
  • Marbled Pim Catfish
  • Red Snakehead (Channa Micropeltes)

We would encourage retailers to ensure that species in the above category 2 are labelled with a realistic adult size, and we stress the need for fishkeepers to check the size of tank that will be required to house them as adults.


3. Other species that don't grow quite as large can still cause problems for the unwary buyer and require rehoming, so they should only be bought by those with means to accomodate them in the longer term. These include:

  • Common Plecs
  • Oscars
  • Red Bellied Piranha

The above lists are by no means exhaustive, but they represent the species and groups that are causing the bulk of the problem.
