I am acclimating some amano shrimp as we speak! Yay shrimp!
I personally prefer Amano Shrimp. They are bigger than RCS, so I feel safer about them being in with my bettas. Not that my bettas have ever shown an interest in them. Chronos will give chase every once and awhile if they are too close to him, but he has never tried to bite them. They kick butt at cleaning too!
Your betta is gorgeous and your tank is looking good.
Just one thing, is that it looks like you have buried the rhizome of your anubias into the sand. You want to raise that above the substrate and have only the roots buried, as otherwise it can rot and the anubias will die.
So we added sponge filters to both aquariums. There seems to be a bit of algae going on in Echo's tank by the Dwarf Saggitaria. Not sure what to do about that. We also added some more friends. There are now 5 amano shrimp in Echo's tank and 4 in Chronos'. The 4 in Chronos' tank seem to be kind of reddish in color. They were like that when we got them and I'm not sure what would cause that.
I pulled up the anubia as far as I could without pulling up roots. I hope it was enough. I pulled up the Narrow Leaf Java Fern in the back as well. The left side of it seems to be doing well, and the right side (while growing) is a bit droopy. The water parameters are fine and all the livestock seems to be thriving. I am sort of just letting it do its own thing. The Anacharis on the right hand side is growing like a weed. For trimming, do I just snip some off the top? Is there a proper way to do it?
We also added Marimo balls to both tanks. The shrimp love them.
They aren't the neatest tanks in the world, but we kind of like the wild look with some of the dirt scattered on the sand. Looks more natural to us. To each their own =)
