My 2Nd Fish Missing An Eye :(

[kylealastairlove]

just realized one of my espei rasbora is missing an eye (one of my brightest best looking ones too) dont even know how it happened but its not the first time.
i have him in a tank with 8 others and a laid back betta who minds his own business! my water parameters are fine but now im starting to think theres a nasty disease in the water

List the water parameters please. What are the dimensions of the tank? And décor?

Very likely, it's the Betta.

 

[kylealastairlove]

parameters are
ammonia 0
nitrite 0
nitrate 10
ph 7.6

the tank is 2ft in length and over a foot in width and height, my decor is just live plants bogwood and rocks!
also i noticed a tapping sound coming from my tank no less than an hour a go, so i take a look and there is the betta darting full pelt at the glass in the corner of the tank, scared me a bit, thought he might damage himself but that may have been a give away sign of a bit of aggression even though he's usually relaxed and seems happy.

Missing eyes are often in the stomachs of other fish. If its a male splendens, then there is no such thing as one that minds its own business in a smaller tank, imo. What other fish are in the tank?

Likely what you observed with your betta was him attacking his own reflection.

yes its a male, hmm well i thought he would have been okay in my tank he never seems aggressive to me unless he waits till lights out time and turns into a very violent fish lol but im not sure, and yes i thought that might be what he was doing, feel like my tanks on a downward spiral now oh well sure i can sort something out
