thanks for all your comments
Betsy is the one with a dodgy eye, and bertha is the biggest one.
that rostrata is the one that grew out of being a yoyo - the new one is in my 2nd tank - helping to get it ready for the dwarf corys and microrasboras i have had my eye on for ages. i was worried about a big fight, so i just put the yoyo loaches in the main tank in case. at least the old fish know the hidey holes - as you see in the bottom of the 2nd pic

mad fish.
Emma that darkest yoyo is one of the originals - the angle of the shot makes her (?) look fatter and you cant appreciate how big Bertha is as she is busy rooting out scaredy loaches

. they are both darkening up, but no where near as dark as the other one in the photo. they are best buddies - no signs of fighting between the 2 of them

they are wonderfull to keep so far. thanks Emma for saving them back for me. if you ever see the person that broutght them in to you, say thanks to them from me.
