Does this tetra have a weird bump on the bottom of his/her belly? Out of the 5 tetras, this one appears to be with one. I did just feed them. Water parameters before PWC are 0/0/10-20. I just did a PWC of 5 gallons out of my 20 gallon tank. Temp is 75. All the fish appear healthy and are very active. Only other habitant is a mystery snail.
