Yes, Seachem Flourish (not excel) with each weekly water change. I do that, root tabs every 3-4 months for my substrate planted plants, and then it's just low tech LED lighting.
I've never looked anywhere but fish stores for my plants. But I bet you could get water wisteria or water sprite from Petsmart. Their plant section usually leaves a lot to be desired but they might have some. Your LFS should have something for you. Or you could always order online, too.
It's made a world of difference, really happy they're doing better. I can't believe how clean the snails keep this tank, it's in direct sunlight. Also snails are reallyyyy entertaining lol
I agree that larger snails can be entertaining. I wanted these awesome golden rabbit snails but I was really worried they'd get picked on/ picked at so I didn't get them. If they were picked on my 5 and 10 gallon tanks are too small I think for the poop machines that they supposedly are.
Hmm I have 4 of them and like 10 little ones, plus the 4 sens in a 30 gallon tank. Wonder if it was too much for the newish bacteria colony, tank has only been up for 5 weeks or so
