Its common use caused its appearance in water environment. VGCC inhibit epinephrine release and cause many neuro-hormonal changes influencing also fish behavior. Siamese fighting fish was chosen to study the influence of verapamil given to the water on the beginning of experiment in 3 different concentrations of 0 (control), 8 and 160 \u03bcg \u00b7 L<jats:sup>\u22121<\/jats:sup>, on aggressive behavior in these fish. The experimental fish were placed in individual glass containers for 3 weeks and the mirror test was used. The highest concentration led to a significant modulation of fish behavior after 1 week and the lower dose caused statistically significant behavioral changes after 2 weeks of verapamil treatment. Siamese fighting fish males exposed to verapamil had longer latencies to the first chase \u2013 12.6 s (8 \u03bcg \u00b7 L<jats:sup>\u22121<\/jats:sup> of verapamil) and 18.8 s (160 \u03bcg \u00b7 L<jats:sup>\u22121<\/jats:sup> of verapamil) compared to 5.6 s in the control group, decreased attack frequency and shorter duration of these attacks. The number of attacks within 10 min was decreased from 38.3 in the control group to 27.1 and 16.1, respectively. Also the total duration of these attacks decreased from 354.8 (control) to 326.4 (decrease statistically insignificant) and to 194.8 s in verapamil treated groups. It was shown, that even relatively low concentrations of verapamil in water may have adverse effects on fish and probably other living organisms.<\/jats:p>","DOI":"10.1515\/pjvs-2015-0051","type":"journal-article","created":{"date-parts":[[2015,7,14]],"date-time":"2015-07-14T11:49:10Z","timestamp":1436874550000},"page":"401-406","source":"Crossref","is-referenced-by-count":8,"title":["Verapamil \u2013 L type voltage gated calcium channel inhibitor diminishes aggressive behavior in male Siamese fighting fish"],"prefix":"10.1515","volume":"18","author":[{"given":"B.F.","family":"Kania","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B.","family":"D\u0119bski","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.","family":"Wro\u0144ska","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.","family":"Zawadzka","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"374","reference":[{"key":"ref31","first-page":"450","article-title":"Verapamil does not modify catalytic activity of in rainbow trout after long -
