Never had pinkies in a 25, but I think one would work. It will voraciously eat pods. The mandarin will as well, so I recommend a Biota mandarin. I doubt you will sustain a pod population in a 25 (AIO?) unless it has a fleshed out sump and daily phyto dosing.
Good recommendations for a firefish or dartfish. In a 25 with smaller fish they will be out more. No clowns? I would also recommend a Yasha goby and pistol shrimp. Have a very good lid with small mesh. The IM lids aren't ok fire firefish, gobies or especially dartfish. Aak me how I know.
You'll have a really cool biome with a pinkie, mandarin, firefish/dartfish, shrimp goby and who know, maybe a possum or a rainford!
Agree. I lost a radiant wrasse through an IM20 lid.

). The other side I have a Skimmer and then a Caddy for carbon, cycle material, etc.
