Here is my first dwarf corydora species tank (not counting the 2 shrimps).
A HUUUGE 22 litres.
Substrate is a mix of river and silica sand and 9/18 river pebbles. A few oak leaves - the cories love them, always snuffling about the edges and up the sides.
Lighting is 7w 6500K for approx 6 hours a day.
3 JBL balls under various crypts, other ferts only when needed occasionally, as per the low tech regime.
Looks a little flat at the moment, partly because it's a small tank and I have chosen small specimens, partly because they are all new and yet to establish.
And yes I have no background so they can enjoy some natural light as well. Later I am moving this up into the living room where there is very little natural light so I will paint the back of the tank.
Plant layout from above
From anubias nana bottom left clockwise: narrow java fern, undulata crypt, cordata crypt, back corner with dark stems and pea green leaves with corrugated edges – mystery crypt (does anyone recognise it?), pearl weed, twisted val, wendtii green and/or brown, affinis crypt. Philippine java fern and Christmas moss on the wood.
7 dwarves. There is one that is visibly larger than the rest, am hoping it's a she-dwarf.
Their tail coloration is not like the one that comes up on google images/aquahobby site in terms of the white at the end of the tail but in the swimming picture you can see a hint of the white.
