I don't know if Mike & co. at Amazon Aquatics (last trading post on Ebay) in Warminster ever courier fish, but Mike has got a tank of captive bred tinanti, bred at his home by his wife!
I came away with a slender 4/5cm male/female duo (too early to say if they are going to become a bonded pair) a couple of weeks ago at the end of my holiday at Longleat Centreparcs (along with 10 Microsynodontis sp.1 and 8 Phenacogrammus cf. nigropterus) and they are such outgoing characters, even after an emergency tank change for them when I discovered they were treating newborn 1.75cm Ilyodon xantusi as "live lunch."
