hello im new and was referred here for questions. i've tried doing search for the help topic but still not exactly sure of my problem or solution
basically one of my two turtles has not eaten since last sunday, they're both very ferocious eaters, as the one that is sick would follow my finger normally just for food before it got sick
now i've tried everything, from waiting out, to taking to vet, to adjusting temperatures higher, feeding them mysis shrimp and bok choy rather than just pellets, and giving them lots of sun light! but the one is still sick
which is worrying me. the sick turtle seems fine too an extent, where it will bask, but won't stick out its arms or legs like normally, it will jump back in water but not swim deep, rather at times just floats around "in between spaces" and water basks there. and is basically lethargic at times. i've tried to put the food right in front of the nose, coat the pellets with tuna fish water, and still won't eat. it won't even open it's mouth anymore.
can anyone help? because the longer it doesnt eat, the more worried i am. i have a feeling some may say its gut is blocked by gravel, in which i do have in my tank, which i didn't know when i first got them they may eat (which i've never observed them doing btw). but regardless if it is the problem and i will remove it if you guys may verify. but if its gut is blocked, what course of action can i do to stimulate it to poop it out? as i heard if it doesn't poop out its feces, it will not eat....
very frustrating, and thank you for reading
