So I've had Xander for a bit over a week now and he's starting to get more curious about his tank. He spent most of the first week in his coffe mug cave. He now roams over every nook and cranny. Anyway, he discovered the filter output today. I put a pre-filter on the input and a plant right under the ouput to slow down the current, but the area right above the plant (about 1 cm under the output) still is rather turbulent. Anyway, he went over to take a look at that today and it freaked him out so much he swam as fast as he could to the other side of his tank! this time a little braver he poked at it again and swam around. For the bast 15 minutes he's been swimming SUPER fast through this little area, I think he's playing in the current!
Also, as a side note, the cave I got him from the pet supplies plus began to CHIP PAINT!!! I took it out but felt bad cuz he LOVED his cave. So I soaked a plan coffee mug in hot water for a while, then stuck that in his tank. 1) it kind of looks cute, and 2) he loves it!
Had to share my little betta anecdote, I'm glad he's feeling more confidant in his tank. Took him a while!
