It's fine for a short video. I put my 13 tiny guys (wishin they would grow a bit better...grr) in a 10 oz plastic cup half filled during 100% water changes on their tank...my reason is to get as low of an amount of stunting hormone as possible into the new water.
Who am I? Well I am a Junior Member of the International Betta Congress and a breeder of white HMPKs, red dragon HMPKs, black/red dragon HMPKs, metallic multi HMPKs, blue masked HMPKs, and now multi color HMs. Soon to add black HMs. I will be showing in New Breeder class in fall of 2012.
