Hi friends! I'm having so much difficulty deciding, LOL! I've kept both in the past, and I've had so much fun with both, but I haven't kept either in a year or so.

It's a low flow tank with sponge filters, neutral to slightly alkaline pH, I don't monitor my TDS and hardness very often, planted with compacta swords and floating frogbit, pothos hanging on back, biostratum substrate, hardscape is driftwood and seiryu stone. Which species will be more hardy and entertaining?

Please help me decide! 😅

Thanks!!
