He's very cool! I love seeing the different tail shapes and colours my current guppy/Endler hybrid tank are throwing! All different tail shapes! Some fairly "normal" guppy and delta types, but also ones like a male that has a tiny bright orangey red tail but swims like a beast after the girls! Most of mine are a blue/purple - I don't know the names for all the tail shapes and colours, and have been meaning to take some photos. Someone please remind me when I return from my one night holiday!
Haven't seen one the same as yours though yet!
I also just bagged up about 20 males, females and youngsters for someone who said her daughter was upset because every guppy they bought died. I explained to her about mass farmed, unhealthy guppies produced abroad and shipped here, and how weak and unhealthy they usually are. She had been stressing, saying she was testing the water and it coming out perfect, doing everything she could, but they kept dying on them. Said I had spare guppies, did she want some? Gave her about 20, mix of males, females and young, told her she wouldn't have the same problem with these, they've been born here in my tank, healthy and robust, and won't keel over in a day or week. She seemed pleased, said I'd be making a little girl very happy, which makes me smile.
