“…In addition to fish, invertebrates are also exploited by ornamental fish keepers in Brazil, although to a lesser extent. Despite the use of invertebrates not being as well documented as the use of fish in fish keeping, it has been recorded by some studies which have highlighted the popularized trade of these animals for this purpose ( Ng et al, 2016 ; Uderbayev et al, 2017 ; Alves & Rocha, 2018 ; Akmal et al, 2020 ). Without considering corals, it is estimated that about 500 species of invertebrates are used in fish keeping, including mollusks (gastropods, bivalves, and cephalopods), polychaetes, crustaceans (shrimps, crabs, and lobsters), anemones and echinoderms (starfish, urchins) and sea cucumbers ( Palmtag, 2017 ; Alves & Rocha, 2018 ).…”
