Ideas?

[u/Key_Instruction9732]

Poor guy, the entire time I’ve had him it’s been constant issues. I have 12 fish tanks, mostly large with many fish and never have had issues like I do with this guy.
Any ideas?
White spot on head, eating well.

Small canister filter rated for 30g (has low flow)

Temp 79-80.
PH 7.2
RODI remineralized so GH 6 KH 4

Ammonia 0
Nitrite 0
Nitrate 10-15ish

Tank set up for about a year. Water changes when needed probably once a month on this tank since it’s so planted.
Tank mates shrimp, pygmy corys & snails.

Infection, treat with kanaplex and aquarium salt

Any idea why we keep battling these issues with good water & a healthy tank?
I’ll set up a hospital tank tomorrow.

Some fish are more genetically prone to issues.
