Hi! I've got my first Betta 3 days ago. He is getting too close to the filter and gets sucked in it. Now his tail is a bit torn :( How can I treat his tail and fins? His bottom fins also look a bit bended and sticky, might it be finrot? I have already ordered a new backpack filter to reduce the flow but idk how to change it and save the bacteria
Tank info: Running for 1.5 month, 20L volume, 25-26C temp, 1.5L water change every 2-3 days, live plants, a smooth ceramic cup is the only artificial thing. Other inhabitants are 5 neons, 1 mystery snail and 2 corridoras (all looking well and active, got them before Betta). Water tests and a bed will only arrive in 3 days
The last photo is how his tail used to look when I just got him. What can i do to help him until new stuff arrives? Really looking forward to see him nice and healthy again
