Development of Dermal Lip Protuberances for Aquatic Surface Respiration in South American Characid Fishes

Copeia, 1989
Thirteen characid and one gasteropelecid fish species from a seasonal swampcreek of the Venezuelan llanos exhibited dermal protuberances of the lower lip during periods of extreme oxygen depletion. Relative frequencies of protuberances showed large interspecific variation and were independent of fish size within species. Protuberances appeared in three

Effect of water calcium, copper, and silver on branchial Na+ permeability in a characid and cichlid fish

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology
We tested the hypothesis that water Ca2+ is involved in control of branchial Na+ permeability in low pH tolerant convict cichlids and black neon tetras. We measured Na+ efflux in water with different Ca2+ concentrations during exposure to low pH, silver, and copper, at levels which are known to stimulate Na+ efflux.

Studies on African Characid Fishes I. The tribe Alestidi (I)

1951
Among a recent importation from the Belgian Congo there was a multitude of lovely little aquariumfishes, mostly well-known to aquarists. but partly new to them, and some of these fishes even new to science. A large number of small ”Tetra’s” closely resembled the well-known species Petersius caudalis.
