black bellys normal or bad fishcare

[Cheeto]

okay so i have been looking at alot of vids on youtube of ceylon puffers and i have noticed in every one of them that they have back bellys. they look like they are way older than mine so i was wondering if ppl on youtube just dont look after their puffers or if its normal for them to go dark when they are older

Tetraodon fluviatilis, is a High end BW fish... so, i think that adults must live on 1.016-1.018 SG.
I used to think that puffers specially celyons and GSP get "blackbelly" for anything, but since i rise the salinity to 1.020 (for GSP) "blackberry" issues has gone away for several weeks.

it may be SG problems, but can be something else, i´ve got no direct knowledge about Celyons, so, lets wait for the topic masters...

it is a good question. All of the ceylons I have seen in person are grey to dark as adults but were not kept in the best conditions... for that answer.. I don't know...
