Cute fish. Is that a macro lens?

yes, Olympus macro 30mm on lumix gx80;)

Wow they are tiny! 15-17mm fully grown. I shall add those to my list!
These tucanoichthys Tucano are amazing,

bold, small, colorful and amazing behavior. They are very rare and can be pricey too, better ask your lfs first.

they have started to breed them in Germany but my lfs guy said that these were wild ones because they lost a lot of the bred ones this year, don’t know exactly why.

it seems that the male keep an eye on the eggs after the breed, which is an very unusual behavior for small tetra!

Hi all,

All these real black-water fish are difficult to keep long term. You need really soft, acidic, tannin stained water for long term success.

Certainly is, and probably related the black-water again, black water fish tend to be unproblematic to feed, because food is in short supply in their native habitat, so they make the most of any opportunities.

Eggs and fry are a prime protein source so parental care is more likely to evolve under those sorts of selection pressures.

Trim needed!

the Tucanos are doing great, feeding them with baby brine shrimps and dr.bassleer since one week seems to have greatly improved their colors.

they are the boldest micro fishes I’ve ever had with males that keep on fighting and sparring like much bigger tetras would do. They are all coming to the front glass when I’m near the tank,fascinating !
