Ok folks, I have been doing the peas for 4-5 days now, and last night I threw in some watermelon, and a few Cheerios. It turns out that my fish have different taste when it comes to different foods, and Has been entertaining and cracking me up to watch them do taste tests! So funny how they will take in a piece, suck on it, and spit it out! Some take it and swim around before they spit it out, and some just take it and just sit there looking like they are considering how it tastes! Man this is hilarious, The Tank (the big plumper) seems as though he is throwing a huge tantrum!!? After he spits his out, he will the attack the fountain wand, he goes at it and hits it with his side, and then goes down where the peas are and zip by with a quick thrust!! He is so mad, well.... That's what I'm thinking anyway? Soon as I threw in some Cheerios, he takes one and just sits there and sucks or chews it and calms right down! Great stuff, thanks for all the recommendations of treats!
