Thanks for the advice!
Sorry, I know I've been making mistakes as I've been learning, but I'm making it so far and my ecosystem as it stands has been thriving. I've definitely got a lot to learn still as I'm far from a professional.
I'm using the fluval stratum substrate and the tank is a 20 gallon long.
Appreciate the thought about the Swords. I've been thinking about taking one or two out anyway, but I've been clipping them and such while watching their health. You may have swayed me into removing one.
My ph is high. And does come out the tap like that. Admittedly, I set up the tank initially without testing the ph of the tap water, so that was my bad. While it was cycling, I tested with strips (not a fan) and attempted to lower the ph, but hadn't stumbled upon more correct ways to alter the ph until AFTER I decided to get amano shrimps. After reading, watching, and talking to people more knowledgeable than I, I've decided it's best keep the water conditions consistent while maybe tapering off the hardness and ph and such over time. Is that right? If not, definitely open to advice.
I'm in no way tied to any particular fish. The guppies appealed to me since I've read they're fairly hardy and will do well in my water conditions. Thanks for the other fish recommendations! I really appreciate it.
I appreciate the help! I know I'm not doing things perfect, but I'm still excited that my ecosystem is thriving!
