Disaster.
The glass cat wasn't looking particularly happy in my smaller tank, there's not too much in the way of cover and the betta was going for him every now and again so I thought last night I'd move him into the bigger tank where there's a bit more plant cover and places for him to hide. I did a big clean on both tanks, and then tried to net him, only he wasn't having any of it and I had to chase him around for ages, resulting in us both getting incredibly stressed out. I eventually got him, moved him to the bigger tank, where he swam headfirst into a plant, wedged himself awkwardly into the middle of it and died about an hour later. I feel bloody terrible. Maybe he'd have been alright if I hadn't tried to move him at all.
It gets worse. I'd unplugged all the electricals when I was cleaning Tank 1 like a good girl, but because the heater is connected to a different unit on the wall, I completely forgot to put it back on, what with the ensuing drama with the catfish. It was only when I had my fingers in the tank this morning to give them their bloodworms that I realised the water was cold. I feel so bad. By rights I should've woken up to a tank of stiffs, right? Please tell me it happens to everyone now and again, or I don't think I should be allowed in charge of livestock, ever! *sigh*
