Abstract: Following behaviour among Neotropical stream fishes have been scarcely reported. This type of feeding association was observed in a small stream in the upper rio Paraná system between the catfish, Aspidoras fuscoguttatus, acting as a nuclear species, and Knodus moenkhausii, Poecilia reticulata, and Astyanax altiparanae as follower species. Aspidoras fuscoguttatus individuals dug in the bottom during feeding, causing sediment suspension. Their followers picked food items in the "cloud" of suspended particles. F… Show more

“…In reef zones of marine environments, the nuclear-follower interaction is an important component of communities, involving a large number of species (Strand, 1988;Lukoschek & McCormick, 2000;Sazima et al, 2007). In freshwater environments, the number of records of this interaction has increased with the increment of the naturalistic studies in these environments; even though, the occurrence of this interaction is apparently underestimated (Baker & Foster, 1994;Leitão et al, 2007;Teresa & Carvalho, 2008;GarroneNeto & Sazima, 2009).…”

“…The presence of unconsolidated substrate and benthic species that revolve or search the substrate are examples of predictor attributes to the interaction occurrence (Strand, 1988;Sazima et al, 2007;Teresa & Carvalho, 2008). However, other factors such as food distribution in the habitat and nuclear species behavior also influence the degree of disturbance caused by the nuclear species, and consequently the interaction profile (Matsumoto & Kohda, 2001).…”

“…So called following association comprise a fish or a fish group that excavate or otherwise disturb the substrate while foraging, and one or more opportunistic species that capitalize on the small animals and other food types displaced by the foraging activity of the former (Strand, 1988;Lukoschek & McCormick, 2000). This association is a well-known one in the marine environment (see Strand, 1988;Sazima et al, 2007 for overviews), although a few instances are reported from freshwater habitats as well (e.g., Sazima, 1986;Baker & Foster, 1994;Leitão et al, 2007;Teresa & Carvalho, 2008).…”

“…Although the cichlids only approached the ray while it was already stirring the substrate, the association is here regarded as following behavior even if a very transient one (see Sazima et al, 2007;Leitão et al, 2007;Teresa & Carvalho, 2008). The association between cichlids and rays was recorded in still water (marginal ponds and dammed river portions), which favors sediment deposition.…”
