I just took a couple of quick pictures of Horatio. I've only had him for a couple weeks, so I wanted to make sure he's doing okay. I'm a little concerned that the end of his fins are a bit frayed. For the first two days I owned him he was in a tiny betta cube with plastic plants, and I'm concerned that they might have frayed him. (Not sure if it's fin rot, though.) I've since switched to silk plants.
As for specifics, he is now in a 2.5g tank, heated, no filter. Today I did a 100% water change. I feed him pellets...3-4 once a day. He seems to be doing fine--he is active and has a good colour, except for the bits of white on the end of his fins:
Hoping for some input!
