why does ranchu drop scales ?

[hobbyist]

what was the root cause of the above ? I only have 2 ranchu and a sucker fish in a 2 feet tank

I change 10% water every 1 day

Was it due to filter ?

Your sucker fish sucked on your ranchu

Yes..sucker(pleco) might be the problem in your tank. They are known to suck on the slime produced by your ranchu..

Tank too small and maybe pleco size is bigger or almost the same as your gf .

yes i do have a big sucker fish.

Does it mean sucker fish only attack ranchu and not other type of goldfish ?

I thot my filtration system is lousy with only 2 ranchu.

Should I remove the sucker fish for all type of gold fish ?

goldfish are slow swimmer so more easy for sucker fish to attack.
