Thanks, fellas!
I'm so happy that I've came back to my ol' "Piranha habits"...!
I had before [for more than 10 years!] Red Bellies, Ternezis and Caribes and also a 25 cm long Rhom.
I was also on this forum when the website was called "predatoryfish.net"...
So as you can see I am kinda... "archaic"...!
Two years 1/2 I gave up all my Piranhas tanks and I've built up and kept many saltwater tanks. Now I have a single 35 gals saltwater tank full of corals, crabs, starfishes and fishes. Two days ago I saw this little guy [Sanchezi] in a pet store next to me [I do live in Montreal Area, Canada] and I took it. It was LOVE AT FIRST BITE...! I've set up high speed a 10 gals tank that I had spare at home and there he is... I am take it step by step now because the Sanchezi - because the poor pet store conditions and because of the stress - got some white tiny spots of Ich. I'll cure him and meanwhile I will look for a bigger tank.
My Sanchezi is ~ 5 1/2 cm long and at pet store was called... "Muda Piranha"... They love to invent names, ain't they?!? Usually Piranhas like mine are called under the "general" mane as "Black Piranhas"...
