Thanks Barbie
I found some photos i took a couple of months ago but forgot i had, some are better, hopefully they'll help check i have a male.
There is five caves, a piece of slate propped up and a piece of wood in the tank for the them, three of them use the caves and one hides under the wood, the final one tries to also hide under the wood, but is chased by the one already there, so sometimes is found under the propped up slate.
The fish are in a totally different order from the first lot of photos.
Fish A;
Fish B;
Fish C;
Fish D;
Fish E;
