I have recently introduced 100 Ramshorn snails in my tank , as soon as I put them there overnight the Nitrite became too high and the spike of Nitrite caused the fishes to come to surface. I removed all of the Ramshorn snails and did a 70% water change which brought down the nitrite.
Now, I notice in the fish tank wall and plants these kind of organisms, when I push it with my finger it feels like meat and bursts.
I have never seen this before, what are these? here is a picture from the leaf of the plant from the fish tank.
