Bleeding heart has some uhhhh thingy on its head, Kinda looks like a horn. Only addition since last August has been airstone(which raised
pH so airstone only lasted 2-3 weeks, and a live plant which brought snails. I killed the plant anyway, been trying to eradicate snails but dd loves them so trying to do it sneakily.
Sorry rambling water parameters
ph- 8
nitrate 5ppm
nitrite -0
ammonia-0
Tried to take a pic, hard to photo fish, looking at him it really looks like a horn is blackish. Any guesses and how do I get rid of?
