BN With red fin tip

[max1zzz]

Hi,
I just noticed one of my BN's has a little bit of reddening on the tip of one of her fins
I'm a little concerned for a couple of reason's, I have lost a couple of my bronze corys recently and haven't been able to figure out why (Water parameters check out fine, and they had no previous signs of illness) but also because the tank she is in is going to be replaced very soon (next weekend if all goes to plan and the shop can get the tank form the supplier) as it has sprung a leak right at the bottom of the tank and I am a little worried about stressing her during the move if she is injured

Any advice would be appreciated
