is my tank size limiting plants?

Bruh, my 5 gallon has booming Anubias. It's all about the light and ferts. You running CO2? Even a tiny dose can help. Also, check for algae blocking light. A quick scrub might do wonders.

Same here! My secret? Seachem Flourish twice a week. Also, keep 'em out of direct light. They're shade lovers, like my ex. Ha!

Yo, timbero, you got any fish in there? My Betta kept nibbling my Anubias roots till I moved 'em higher. Could be your plants are stressed from more than just tank size.

Anubias be chillin' in my 20 long with zero issues. Maybe your tank's too clean? Sounds weird, but some plants like a bit of dirt. Try skipping a water change and see what happens.
