here is what the tank looks like now

i did add a large piece of wood and some small bits from my other tanks into that one
Branches arent that common to find in LFS in canberra
and i dont plan to use trees out side our home-way too risky and too much work!
i did dim the light with some foil
and there is a strong large air stone which gives the tank a mild current
im getting the male tomorrow
its really hard for me to find a good decent pump.
this is because my parents dont trust internet sites to buy off except one. and even then they dont trust it that much!!
now all i need is a edible cave for them!! iwas thinking bamboo but i havent found any of those in a long time or maybe cocunut but i dont know how to boil it and remove the meat and such-and then again i havent seen a large brown cocunut in are local supermarket
and now im gathering some info across different forums on how to breed them
so far i plan to:
let the male settle in for 2 weeks or so with normal weekly water changes with vacuum
after he has settled in,chosen his cave etc., i will stop feeding my fish and let them be but removing water by vacuuming, this will take about 2 weeks
then after the 2 weeks im going to fill up the tank slowly every day with cooler water than the main tank with normal dechlorinater (dont have access to RO water) but if it does rain i will use the rain water to fill up the tank OR when it rains just fill the whole tank up slowly with colder water
then see what happens there
how does that sound?
if there is anything that needs adjusting, please tell

thanks in advance
btw does anyone know what that large floating plant is? it has no roots too.
it came with my ambulia that i got from an auction so i though it was part of it but it slowly came off (maybe it was tangled?) and now i have this nice big thread like floating plant!
if you need an another picture to id the plant please tell
