The left female stingray seems to grow slower and seems to be skinny, it has been worse…
I have treated with Sera Tremazol 2 rounds already.
They have 20cm each.
I feed once a day and switch food everyday, shrimp, mussels, scallops, sardines, krill, bloodworms and squid.
They arrived same size but male is now bigger, female is smaller skinnier and never eats fully… and has a slight dent on head which has gotten better since last treatment.
Also I live in Europe so its hard to find medicine for fish.
What can I do?
