Mr. Nicholson - I have to disagree with you 100%.
I have been REALLY trying to stay out of this conversation because I don't want to have an argument with someone who is equally, if not MORE, sarcastic (when I NEED to be, and only then) as myself. But when I read the statement where you'd match wits with anyone anyday, I'll take you up on that offer. I, too, am not whatsoEVER afraid to match wits with someone - especially a VERY closed-minded person.
SO... I have 12 tanks right now - all filled with bettas.
I, too, use colloidal silver in my tanks. When the fish see the bottle come out, the go and hide in a cave, behind a plant, etc. because they know I'm going to dump something scary into their tanks. I have tried keeping the bottle away from them and using a medicine dropper to add the colloida, but they know. They KNOW it's not feeding time so something must be suspicious.
When they see me coming at them with a bowl (AND.. my bowls are ALL different colors, red, green, blue, butter yellow, etc.) they know they will be fed either peas or bloodworms.
SEVERAL of my fish also know when I'm done feeding them - I ALWAYS give them 4 pellets in the morning, so when I'm done dropping the 4th one in, and they're done eating it, they swim away to go find something else to do.
ALL of my fish know me - and I too look very different from one day to another. I have long hair - sometimes it's up, sometimes it's down, one day it's dark brown, the next day it's blonde (okay, I dont' do this very often but it recently happened to me lol) ANYWAY.. my point is - they know me and come running (or swimming) to the front of the tank when they see me. Anyone else comes by and they hide.
I have one fish that's VERY playful - he's my tail-less betta, Lucky. He is VERY smart. I do the "run your finger along the front of the tank for fun" game with him, but he eventually gets bored. I have had to change it to hide and seek with him - where i reach around the back, sides, top of the tank where I "peek" a few fingers out at him. he is smart enough to look, up, left, right and behind him because he knows that's where I'll be.
I'd have to say that these fish have more personality, intelligence and integrity in their little fin than some people have in their entire body.
