What's Attacking My Cory's Eye's.

[doodleing]

I have a fishless cycled 4 ft 260 ltr tank with normal water reading. The tank is heaverly planted with silk / plastic plants. There are a dozen cory's of different types, female betta's, harlaquins, tetra's, a dozen dwalf ciclids/ rams, a clown plech and 4 zebra loach.

I have had for the second time now awoke to find a cory with it's eye's missing, the first was a small peppered with one missing which was placed in a breading net and is still alive that was 2 week's ago. This morning i have found a julli cory with both eye;s missing but sadly dead.
My only suspect is the Zebra loach which seem to have a little redness around there mouths or is this somthing else.
I'm also treating for white spot which a bolivian ram brought in 10 days ago.

It could be the zebra loach but I would be more suspicious of the rams, they and the cory's are pretty much wanting the same space but a cory wont put up a fight.

What type of Rams are they?

I have the Bolivian Rams and Corys and they mix together really well!

Dwarf cichlids may be small, but they still have attitude and claim territory at the tank bottom... I'm not surprsied your corydoras are having a hard time!

Depending upon the types of cichlids you have, you might just about get away with two groups, a pair and a hareem trio. What types of cichlid do you have and how many of each type?

Due to the armour on corydoras' flanks, it is often the eyes that get removed by opportunist fish that spot a dead one, but some cihlids like Kribs are reknowned for attacking corydoras' eyes while they are still living.

That was my first theory but what watching them every day the rams and cory get on fine. The only fish that bump into the cory's are the zebra's and other coty's.
The cory's i have (forgive the spelling) are Netted, Julli, Adolf, Axolrod's, peppered, albino, panda' and striped.
The rams are bolivion, neon blue, double red agassiz, macmasters, three striped and checkered.

I would say its the cichlids causing harm to the corys.

Its not really advisable to keep corys/cichlids together due to the aggressive behaviour of cichlids,these will harm & easily kill placid corys...
