This study aimed to elucidate the responses of the Neotropical fish Lophiosilurus alexandri exposed to ammonia and nitrite, following a period of recovering. Acute toxicity tests lasted 96 h, subchronic toxicity tests lasted eight days and the detoxification trial lasted four days.Groups of 12 juveniles were maintained in 90-L tanks and treated with increasing concentrations of ammonia and Teleostei (teleosts) > Siluriformes (Catfishes) > Pseudopimelodidae (Bumblebee catfishes, dwarf marbled catfishes) Etymology: Lophiosilurus: Greek, lophos = crest + Greek, silouros = cat fish (Ref. 45335).

A total of 48 juveniles (360.0 ± 141.6 g) were distributed among eight tanks (120 L) and subjected to hypoxia condition (water with dissolved oxygen at 2.12 ± 0.90 mg L−1) or normoxia (at 5.60 ± 0.31 mg L−1).
