[quote=MSG;1355398]That's why I remove ANYTHING that might scratch up their eyes.
When my bettas are hunting for food, they are 100% focused on the prey. Mine will launch themselves towards rocks if they think a meal is waiting for them.
The only decoration in your tank that could have damaged his eye was probably the lava rock.
Also when a fish is skittish or easily startled, they can bash themselves up against sharp objects. Hence the occasional missing scale for some fish.
When you factor in the amount of time & medication it takes to treat a injured fish...... euthanizing is easier.
Those medications you're using are above my skill level. No experience with them[/QUOTE
You're probably right about the lava rock. I completely re-scaped his tank and the lava rock has been moved to my 29G.
