help with dead marble

[lo sai]

I lost my Marble this week and I don't know why.
Some help would be appreciated.

Female marble. WC had it for under 2 monthes, treated with prazipro
It ate fine and then I noticed its appetite get smaller and became skinny.

tankmates: 2 CB leos and a red aro.

Water:
pH - 7
Nitrite - 0-0.3
Nitrate - 0
amonia - 0.1

The disk looks rather chewed, did you notice the leos harassing it?

no aggression, just the occasional cup on top when food is around...
in the day they are fine but at night I have no clue.

Definetly look like bite marks to me.

Elevated stress caused by tankmates = diminished appetite. If the problem isn't solved the ray will starve to death.

In my experience Marbles do not handle stress well at all. Doesn't matter if it's coming from water conditions or tankmates. They seem to have such small tolerances to stress that they almost seem to commit suicide if unhappy.

I'd also be questioning water parameters. Small amounts of Nitrite and Amonia with ZERO Nitrate isn't a good sign.

This doesn't look like disc rot and arowanas tear instead of bite so I'm suspecting your leo was being agressive? How big are your leos? Any males?

i had to seperate me leos from motoros. the leos are just too aggressive

i agree w DB, ur tank isnt cycling correctly. this is deff stressin your rays
