I have API Stress Coat.
After going to Walmart and not liking the selection of kits, I just pieced together my own with a basic 10 gallon, a Tetra Whisper filter (which is REALLY loud, going to be switching that out soon for a Fluval, yeesh.) and a clip-on lamp with a CFL in it. Plus one of my spare heaters.
So, I went and purchased the betta, who although looked pitch black in the store in her (!!) bowl, is actually a caramel brown with black stripes and iridescent scales, with hints of color in her fins. I'm pretty positive she's female. I spent an hour slowly drip acclimating her, and released her into the 10 gallon. It has no substrate atm, I'm waiting for it to come in from amazon. I've got a large amazon sword, a clump of ludwigia, a clump of elodea, so water lettuce, and a few bits of duckweed hanging out, along with several small java ferns on a piece of driftwood.
She's been investigating everything, she swims up to things and stares at them and circles them, then moves on. I've kept the light off to keep her calm, and I probably won't turn it on until I get the substrate in. She's been 'hunting' a bit, anything that's small enough to fit in her mouth she tries to eat. I don't think I'm going to feed her today though, just in case.
I'll post pictures once I get the substrate in, and have the light on :)
Also, I've named her Lionheart. :) Now that I know she's a she, is it alright if she's kept alone? Or do females need a sorority?
