Thanks for inviting me to post this here!
This is the 'fancy' betta hammock I made for my only AB betta I own. I made the typical DIY betta hammock from plastic mesh (available at any craft or Walmart store) and cut it so there'd be amble room for the betta to go in as well as my hands to work in it.
I added two suction cups for stability, since I planned to add silk plants to it as well.
Then I found some old decor that I'm not using and doubted I would use and trimmed off the silk plants connected to it. You could also buy silk plants specifically for this, I was simply home and bored.
Any ways, most silk plants have plastic stems you can poke through the holes in your hammock. I chose to weave it through a few holes if I could, just so it was secure, but also so I could tuck the ends away from the inside of the hammock so as not to disturb my betta.
You can do whatever you like with this, I chose to position some broad leaves in front of the 'door' so s to create more cover for him when he chooses to use it (which he does off and on still).
It's durable and safe (make sure you check for metal parts and remove them - rust is very bad for your fish! ), and you can easily change up the foliage whenever you like.
