If you keep cichlids for any length of time, you are sure to need a variety of medications at some point, especially if you don’t quarantine new fish. From treating exterior wounds to internal parasites, there is a medication for nearly any malady.
Yes, I have a blind cichlid, a Neolamprologus cylindricus to be exact.
How do I know he’s blind? Observation.
How much do you care about your fish? Seriously. Are they “just fish” to you? Or does the death of one of your fish really bother you? Maybe the effect on you is somewhere in between.
