PO­TA­MOTRY­GON JABUTI

Practical Fishkeeping (UK) - - Species Showcase -

From Brazil’s Rio Ta­pa­jós basin, this ray has only re­cently been de­scribed as P. jabuti, al­though it’s been known in the trade for some time as the Pearl ray.

Ju­ve­nile coloura­tion tends to be rea­son­ably drab with a num­ber of eye­spots, but adults can be ab­so­lute eye candy with the best spec­i­mens fea­tur­ing in­cred­i­ble mar­bled pat­terns. There can be con­sid­er­able vari­a­tion in coloura­tion, but breed­ers at­tempt to ob­tain the most strik­ing con­trast in shades and en­sure the ring-like mark­ings re­main un­bro­ken. Ex­pect to pay se­ri­ous money for a top-grade spec­i­men.

This species tends to have an ‘arched’ ap­pear­ance, hence the species name – ‘jabuti’ refers to an Ama­zo­nian word for ‘tor­toise’ in hon­our of this ray’s un­usual pos­ture. Pro­nun­ci­a­tion: Poe-tam-oh-try-gone jab-ow-tee Size: 45cm Ori­gin: Rio Ta­pa­jos Habi­tat: Sandy and muddy rivers and pools Tank size: 250x90cm foot­print Wa­ter re­quire­ments: Soft, acidic; 6.0 to 7.0 ph, hard­ness 4-12°H Tem­per­a­ture: 23-26°C Tem­per­a­ment: Preda­tory, peace­ful with larger fish Feed­ing: Large meaty foods, fish pieces, prawn, earth­worm Avail­abil­ity and cost: Un­com­mon in spe­cial­ist stores; £250 to £350
