So I just got my new betta yesterday after Orion passed away :(
Betta was in absolute perfect condition and I look this morning and his back fin has a split in it! OMG... It has to be the rock decoration I have because I have all live plants and I muted the filter with a plastic bottle. He is perfectly healthy! I took the rock out. My other fish like the cories and neons like it. Is there anywhere I can get smooth decorations? I could not find any online.
Will this heal up quick? Here is a picture. I love this. He's flaring at himself :)
