Tõesti, ka selle foorumi leheküljel on korratud levinud väärarvamust, et Dermogenys tunneb end soolases vees paremini. Ent nendesamade linkide all leidub ka kogenud kasvataja kommentaare, mida ta toetab raamatutarkustega, mistõttu kipun neid tõe pähe võtma:
„As I understand it, most halfbeaks are marine, and those are all egg layers. Only the freshwater species are livebearers (

Sealsamas:
„No, wrestlers (Dermogenys spp) don't need salt. TOTAL MYTH. The author of the Aqualog book puts this down to juveniles of marine/estuarine halfbeaks having been mistaken by earlier generations as the wrestling halfbeak. That said, they do fine in slightly brackish IF YOU WANT TO put them there.”
Lisaks segiajamisele mereliste suguvendadega, võib otsida Dermogenyse soolalembuse juttude tagamaid sellest, et sarnane liik Nomorhamphus ebrardtii võiks tõesti vajada väheke soola oma elukeskkonnas:
„The only Nomorhamphus that occurs in slightly brackish water is N. ebrardtii, and I have observed that while it can survive in soft/acid water, mortality is high. It almost certainly needs at least hard/alkaline water. If it is sold as a separate species, it's the "red fin halfbeak", but I've only ever found my specimens of this mixed in with regular Celebes halfbeaks (Nomorhamphus liemi liemi) (
http://www.fishforums.net/index.php?showtopic=141772).”
Lisaks kõigele, võib Dermogenys tõepoolest ju taluda soola lisamist, ja mõningal juhul end siis ehk pareminigi tunda, kuid arvan, et selle võib panna parasiitidele ebasoodsama keskkonna loomise ja vee mõnevõrra suurema stabiilsuse arvele.
