Don't worry...ANY spelling errors are forgiven...we all do them. I am somewhat curious about keeping squids also...loligo should be able to be kept in a large tank...has anyone done that???
p.s. please forgive any (sic)s I may make too!
Cuttles will naturally have more fish in their diet than an octopus would and I used a fair amount of fish for my cuttles but make sure you still have a varied diet and maybe take days about between fish and crustaceans
When I fed my cuttlefish gamma frozen fish, old scratches on their backs used to whiten frighteningly. Feeding shrimp (live and frozen) allowed the problem to fade back slowly.
My system used live rock, sand and a skimmer, so was nowhere near sterile! Nitrate was higher than ideal due to food input levels.
Joel, keep a close eye on what the cuttle is doing... he may be bumping into the glass or rocks etc... I had seen that on one cuttle i had that never seemed to watch where he was going and would get abrasions on his eyes.
Also, this is hopefully premature, but cuttles eyes do give away the start of senesence... they get a type of cataracts effect, is that what you are seeing or is it a fungus?
