+1 for actually selecting a blackwater angelfish for a blackwater tank.
just start with the bigger tank, 75 would be pretty nice.
be selective with your manacupuru angelfish selection….many angelfish come from Manacupuru, most of them aren’t red shouldered.
Battery powered air pump for the cost effective win. Generator for the mega win.
With that said, oxygen is paramount. Bacteria can go a long time without eating, but they need the o2. When it shuts off, you'll need to pop the lid off the canister filter, cans are cool but they go hypoxic (sp?)...
I'd burn half of it, invest the other half in an index fund when the market corrects, and be stoked I didn't lose all of it on fish.
If you kind of already know what you love, and have the skill set to monetize it, Id allocate 5K in capital, and still go index fund with the rest later.
I 100% buy into this. As a fisherman, a low pressure system will destroy good fishing for salmonids quickly. Steady barometer is fine, rising is fine, falling and I'll just stay home. I've always speculated that it had something to do with swimbladder.
One Apistogramma is fine. A pair of breeding Apistogramma are still not fish to share the bottom 1/3 of the tank with anything that's not a sacrifice regardless of how densely planted it is..
This isn't hyperbole, this is 300 pairs, of 50+ species of Apistogramma speaking.
^^^ Yeah, a lot of what was said above. With just 1dKH (17.9ppm), your bacteria will be able to process just a hair more than 2ppm of ammonia ( 1ppm ammonia takes 7ppm of KH to process), with less than 1dKH....they aren't going to be able to do much.
