For the first time in a long while, I went to the specialist fish store and returned with a haul. All but two of my regular neon tetras are gone so now that I have income I decided to try wild cardinals. Got 11 to start with and I'll add more over time in batches so I don't implode my wallet all at once lol. I also got 4 young angelfish for a larger centerpiece species and an unexpected addition, a marbled whiptail catfish. Saw some of them at the store, had no idea what they were but was immediately smitten. Decided to pick one up after a little research.
Not taking any chances this time though and immediately got them started on an Ich X treatment regimen. Hopefully they'll all be fine.
I also got a plant-growing substrate that I'm going to gradually mix into the black sand, since even the vallis, despite having taken over the whole tank, are looking a little sad these days.
