clamped fins and tilts body

hi guys i need your help again!

i've tried following your advice to change the diet. i now feed my fishes mainly meat ( a blend of shrimp meat, mysis , brine, fish , squid and stuff ) . they are eating it okay . but my maroon clownfish's poo is still stringy and greenish, a whole world difference from how it used to be. it's also very very thin. so i'm thinking she's pooing out very little of what goes in, making her stomach a little bloated. could it be intestinal problems since the poo is definitely not white ?

ps. the stringy i meant is not really like those long stringy ones when they have worms inside, this poo is quite solid, always about 1 cm in length.

more info: the fish was treated for ich with hyposalinity for around 3 weeks. could that have caused problems?

thanks in advance!

 

update : i asked my LFS about the fish's poo, he said it might be his intestines failing hiim due to cyanide poisoning.. all the fishes here are caught that way , no tank bred. i'm so afraid there's nothing i can do to help my fish

from extract :
Fish are approximately one thousand times more sensitive to cyanide than are humans. Dose levels as low as 0.03 mg/L HCN can be ultimately fatal to sensitive species, while 0.2 mg/L is lethal to most species. Many of the fish exposed to cyanide die immediately, especially the younger and smaller fish.

Fish that survive the initial poisoning sometimes don't show signs of their exposure until days, weeks, or even months later when they die from shock or MASSIVE DIGESTIVE DAMAGE.

 

My algae blenny flexes its body once in a while after it's done eating.....It's like he's trying to get things moving, LMAO.
