Recent studies have shown that TS also plays a role in regulating social interactions in fish by reducing aggression between individuals. While this effect may stem from decreased aggression in dominants, the potential contribution of increased appeasement behavior in subordinates has been overlooked. Here, we investigated whether TS facilitates the onset of appeasement behavior in the cichlid fish\n                    <jats:italic>Geophagus iporangensis<\/jats:italic>\n                    , a species that exhibits clear dominance-subordination relationships. Isolated individuals were assigned to one of two treatments, either with TS (provided by plastic sticks lined with silicone bristles) or without it for 21 days. Then, each fish was paired with a socially experienced dominant individual to enable rapid hierarchy resolution. Initial appeasement scores did not differ between treatments. However, individuals who experienced TS exhibited significantly higher appeasement scores during the final 5 min of the contest than the control group. Additionally, fish under TS showed an increase in the appeasement score after 10 min of agonistic interaction, while it did not change in the treatment without TS. Overall, this study provides the first evidence that TS can mitigate aggressive interactions by intensifying subordinates\u2019 appeasement behavior, thereby affecting social dynamics similarly to mammals.\n                  <\/jats:p>","DOI":"10.3389\/fnbeh.2026.1821679","type":"journal-article","created":{"date-parts":[[2026,8,20]],"date-time":"2026-08-20T05:27:52Z","timestamp":1787203672000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Body tactile stimulation intensifies appeasement behavior in a cichlid fish"],"prefix":"10.3389","volume":"20","author":[{"given":"Bianca Cambiaghi","family":"e Silva","sequence":"first","affiliation":[{"name":"Departamento de Ci\u00eancias Biol\u00f3gicas, Universidade Estadual Paulista (UNESP)","place":["S\u00e3o Jos\u00e9 do Rio Preto, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ana Carolina dos Santos","family":"Gauy","sequence":"additional","affiliation":[{"name":"Departamento de Ci\u00eancias Biol\u00f3gicas, Universidade Estadual Paulista (UNESP)","place":["S\u00e3o Jos\u00e9 do Rio Preto, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah Garcia","family":"Prado","sequence":"additional","affiliation":[{"name":"Departamento de Ci\u00eancias Biol\u00f3gicas, Universidade Estadual Paulista (UNESP)","place":["S\u00e3o Jos\u00e9 do Rio Preto, Brazil"]},{"name":"Centro de Aquicultura da UNESP","place":["Jaboticabal, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manuel","family":"Gesto","sequence":"additional","affiliation":[{"name":"DTU Aqua, Section for Aquaculture, Technical University of Denmark","place":["Hirtshals, Denmark"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marta C","family":"Soares","sequence":"additional","affiliation":[{"name":"CIBIO, Research Centre in Biodiversity and Genetic Resources \u2013 InBIO Associate Laboratory, University of Porto","place":["Vair\u00e3o, Portugal"]},{"name":"BIOPOLIS Program in Genomics, Biodiversity and Land Planning, Centro de Investiga\u00e7\u00e3o em Biodiversidade e Recursos Gen\u00e9ticos","place":["Vair\u00e3o, Portugal"]},{"name":"CIBIO, Research Centre in Biodiversity and Genetic Resources, InBIO Associate Laboratory, School of Agriculture, University of Lisbon (ISA)","place":["Lisboa, Portugal"]},{"name":"MARE\u2013Marine and Environmental Sciences Centre\/ARNET\u2013Aquatic Research Network, Institute for Research and Advanced Training (IIFA), Universidade de \u00c9vora","place":["\u00c9vora, Portugal"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eliane","family":"Gon\u00e7alves-de-Freitas","sequence":"additional","affiliation":[{"name":"Departamento de Ci\u00eancias Biol\u00f3gicas, Universidade Estadual Paulista (UNESP)","place":["S\u00e3o Jos\u00e9 do Rio Preto, Brazil"]},{"name":"Centro de Aquicultura da UNESP","place":["Jaboticabal, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,8,20]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"7346","DOI":"10.1038\/s41598-018-25513-6","article-title":"Monoaminergic levels at the forebrain and diencephalon signal for the occurrence of mutualistic and conspecific engagement in client reef fish.","volume":"8","author":"Abreu","year":"2018","journal-title":"Sci.
