Pea puffer with red lump on chin area

Hi,
My pea puffer (1 of 5 adults in the tank)has a red lump under her mouth - where a chin would be. The lump is getting quite large.
My water parameters- nitrites 0, nitrates 0 , ph 7.
The tank was established about 9 months ago, and was cycled and established with guppies and corys for 3 months.
I feed them live black worms and daphnia from a culture tank every other day.
I recently found damselfly larvae babies in the daphnia culture so I now don’t know exactly what else has gotten in there.
Tankmates - 9 cherry shrimp
Tank size - 3 feet approx 120 litres
26.5 degrees - it was 25.5 degrees. I put it up when I saw them mating.
Heavily planted
All 5 fish were brought up from juveniles together and are about 8 months old.
She is breeding well but the other 4 peas turned out to be male so she may get a lot of attention.
I have 2 sponge filters and 1 small flow filter in there, 1 bag of bio noodle since day 1.
Any help would be appreciated
Thanks

Unfortunately, I have been seeing this a lot--even with some of my own DPs. From all the research I have done, nobody seems to know the cause but they don't live long after this bump develops.
