Does your clown­fish lack per­son­al­ity? It might be nor­mal!

Practical Fishkeeping (UK) - - Fishkeeping News -

re­search in aus­tralia has been car­ried out to de­ter­mine the ex­tent of in­di­vid­ual per­son­al­i­ties in clown­fish (anemone­fish) species, Am­phiprion.

The re­search in­volved in-situ anal­y­sis of key per­son­al­ity fea­tures – bold­ness, so­cia­bil­ity and ag­gres­sion – in Am­phiprion mc­cul­lochi and Am­phiprion late­zona­tus.

Be­hav­iour ap­pears to be linked to en­vi­ron­ment. A. late­zona­tus, in­hab­it­ing a rel­a­tively sta­ble la­goon en­vi­ron­ment, were char­ac­ter­ized by uni­form be­hav­iour, while A. mc­cul­lochi, sub­ject to a harsher habi­tat and with more so­cial flux, showed vari­a­tion be­tween in­di­vid­u­als – they could be more so­cia­ble, or much bolder, than other A. mc­cul­lochi in their neigh­bour­hood. The ram­i­fi­ca­tions of this for the fish­keeper is that if you want a staid, pre­dictable fish, you should opt for species that come from sta­ble en­vi­ron­ments, while if you pre­fer a wild card, then go for fish from un­sta­ble ar­eas.

clowns’ be­hav­iour may de­pend on the habi­tat they came from.
