I have recently made a few changes to my established tank.
During a 3 hour process I added a Large piece of Malaysian Driftwood Which I soaked for 2 days in non-chlorinated water. And decided that it would also be a good time to clean the filter and do a partial water change.
The next day I noticed a few changes. I'm not sure if I'm just being over cautious because of the new changes or not but wanted feedback.
The Bala Shark's Fins seem Jagged and torn (Possible Fin Rot?) As well as one of the 3 Angel fish.
The Tetra Is constantly trying to Swim UP but is not bloated or showing any other problem signs and after mentioning it my girlfriend seems to remember her doing this for quite some time. Is it common perhaps?
Also look carefully in the picture I am going to attach do you see 2 (rust) spots on the Bala Shark's side? every once in a while I catch a glimpse of this from him as he's swimming around.
...Out of concern I started treating the tank with aquarium salt but not a full dose because Im concerned I will injure the scaleless loaches.
Just today I added 5 Planted Java Fern to the driftwood. After I noticed these problem signs. My questions are should I be worried about these Signs if in fact they are signs of distress at all.
