HAham yeah I've read the whole "female betta/breeding heated debate" in Trapper's thread..gonna stay away from that...
Jim, the blurry fish in pic 2 is one of the Endler's Males...but basically they look just like guppies with slightly different colors/patterns and there is argument that they are guppies. At one time they were classified as guppies, then considered wild guppies, now still debate and I am not totally sure what they are exactly other than cute and colorful. Anyways they can breed with normal domestic guppies. Perhaps I will try to get a pic of them but the little buggers don't really ever slow down for a pic.
Trapper. Here are my best tips on how I decorated my tank for you to snatch as your own if you like. I got those rocks just from random places outside. Lots of them collected from walks, along beaches (I live near freshwater lake so no worries about salts), etc, which were just laying around decorating some gardens and walkpaths around my house until I snatched them for my tank. I don't think any of them are specifically slate but just avoid using limestone or crumbly sandstone rocks.
I used black and green thread to tie the java moss and some java ferns to the top of the flat rocks for the cave bridges. The java moss effectively grows around and up to hide the thread quickly and the java ferns have roots that can anchor them to rocks and thread later removed or the thread just kinda camouflaged as roots.
The floating bundle of java moss at the top is sitting on top of a cork, otherwise it always sinks to the bottom nearly immediately. It just sits on top of the cork and drapes over and around to hide it completely.
In the back I have a small piece of plastic needlepoint canvas that I was working on covering with java moss and java ferns tied to it with string trying to make a background of plants and to give added height since most of my plants are short but I ran out of plants to completely hide the white plastic canvas so I'll need to finish that later.
