Randomly in a little 6gal, only a third filled, no heater, sponge filter
The only thing I had in there were plants, some assorted coldwater ones for my patio pond, some for a British native tank, and then an order of crypts.
I don't know what it is or how it managed to grow to that size, it must have been eating microorganisms in the detritus?
Still trying to ID it, if anyone knows about it? I'm thinking some kind of pencilfish or neolebias?
Pencil Fish - #Nannostomus The #PencilFish is a great fish to keep in an aquascaped aquarium. These fish are not normally seen in the fish hobby and make great additions to community fish tanks. They prefer softer and slightly acidic water. Size is about 3/4" to an inch. www.petzonesd.com/pencil-fish-nannostomus (at Pet Zone Tropical Fish - Kearny Mesa, San Diego, CA) https://www.instagram.com/p/BtkhociBIC4/?utm_source=ig_tumblr_share&igshid=3p4nl2y9yn7t
