Well some negative progress. My betta (I really need a name for him) managed to put some holes and blow part of his fin.
I haven't a clue how he managed to do this, his tank is empty. I removed the dangerous fake plant, and nothing else in his tank is sharp or pointing. Maybe the lack of hiding places is stressing him out and making him flare more, but there is nothing much I can do until the bulbs I have planted in his tank get bigger. Right now they just started to grow, and are about 2 to 3 cm long. On the brightside, he is recovering from the fin rot. Any advice?
