Hi everyone! I am finally getting my new gravel and am all set up to clean it, and my betta has either gotten fin rot again or his fins have been damaged by being netted the other day. As a result, I'm reluctant to net him again while I clean and add his new gravel. However, I was wondering, if I clean the gravel and have already done a last rinse/soak in dechlorinated water, can I use a fish net to bit by bit scoop the gravel in, while he's still in the tank? This won't be quite as tedious as it sounds as it's only a 3.9 gallon tank. But will this hurt him in any way, if I lower the gravel right to the bottom in the net and then turn it over, not drop it in from a height where it might fall on him?
