Just performing routine maintenance yesterday and I pushed some gravel to the side against the bottom rocks in my tank. This was because I was trying to scoop up the diatoms that popped up on the gravel. Little did I know, I trapped my beautiful flame Angel in the rocks work. Didn’t realise until he didn’t come out this morning. I found him battered and gasping on his side in the rocks and had to move everything to get to him. I tried everything I could in the least stressful way to save him and he died shortly after. I can’t believe that happened, he was very healthy and beautiful. Has anyone else made any stupid preventable mistakes that cost them their favourite fish?
