Common pleco 5 yrs old noticed the growth before moving to the new tank.

75 gal tank I let cycle for 2 months fish have been in 6 weeks.
Ph 7
Ammonia 0
Nitrite 0
Nitrate 40 (a bit high)
Penn plax 1000 and a Rena filter
Water change 1× a week about 30%

Tank mates
2 bala sharks
3 zebra loach
2 upside down catfish
9 tetras

I also posted 2nd pic either here or on one of the forums or both can't remember. Growth under gill. Some one said cancer or tumor.

I'd like to get thoughts on what's on the first pic? then maybe 2nd pic
