--------------------------------
So I got this 1/2 gallon
Marina Betta Kit and decided to throw in 10 male Bettas.
Just kidding
Got this as a shrimp quarantine tank ($7) and because it looked neat, but ended up populating it. Grabbed a
Hagen Elite Mini filter ($7), stuffed the hell out of it with sponges (superglued to intake also).
Make-shift 3 layer filtration: added 1 mini-packet of
carbon, and 1 mini packet of
biomedia (both cut and sowed). Flow @ a trickle. Output angled up to water surface to create movement and not dislodge sand.
Fauna: 12 RCS, 3 MTS
Flora: HC, frogbits
Substrate 1/4" soil, some Fluval plant stratum, Tahitian moon sand & small gravel (only had white) cap
Water top-off daily, 30-50% change/week. I think the size works for RCS, but I'll be moving most over to my 9g when it arrives (unbroken hopefully).
