Pet Forum / Aquaria / Marine Reef / April 2006FISH Going BLIND !
Hello, Does anyone have any idea why my green chromis are going blind??? This is the second group of 3 that have done this. I've had the tank for 6 yeas ( 75 gallon) and Still have some the original fish . A yellow tang and yellow tail Damsel. They are NOT losing their sight. Neithe r are any of the other fish ( as far as i can tell) My light is a 40 watt 50/50 Coral LIFE on for 8 hours . I also have 2 - 65 watt split actinic /daylaight compacts on for about 5 hours. ( about 15 inches above the tank. They bump into things and are having a tuff time finding food. If they bump into a floating piece, they might get it. The last batch eventually died. Could the phospors of the 50 50 have changed ???? I have coraine algae all over everything and hate to change the light. And why just the Chromis??? Russ I know certain breeds of fish will develop blindness over time if they are not given a well rounded diet. Example a Volitane Lionfish that eats nothing but freeze dried krill can develop blindness, lockjaw etc. Avoid that by feeding same fissh krill, shrimp parts etc. as far as your green chromis no clue but might be that. >Hello, > [quoted text clipped - 12 lines] > >Russ I think the fun part of having a lion fish is to feed it pink minnows and watch him stalk them.

Even though they were quarantined properly, they seemed less robust than any of my other fish. Some got white "fungus" patches on them, and if there were any white marks near their head, it seemed to get into their eyes, and make them blind. I think many of them are from the Red Sea, which is higher salinity than most other places, or perhaps the collection and storage procedures are incorrect. A great pity, as they are beautiful fishes. Regards, Fishnut. Yep for a $4.99 fish they sure are pleasant to look at. Oh well when these go that's it. It might be a salinity issue. I keep my SPg at 1.019 instead of 1.023. >>Hello, >> [quoted text clipped - 28 lines] > > Regards, Fishnut. the salinity for them is to low,slowly adjust them to it or raise it to that > Yep > for a $4.99 fish they sure are pleasant to look at.

I keep my SPg at 1.019 instead of > 1.023. 1.019 ???? Do you realize the Red Sea is more salty than other reefs ? The salinity in the Persian Gulf is very close to 40ppt (1.029 sg) instead of 35ppt (1.025 sg) on the ocean reefs due to the unusually high evaporation rates. Animals from this region should be kept in the higher than normal salinity and temperatures... I never thought a lower salinity would cause blindness. I've kept it low ( around 1.019) for years hoping to keep the ich from developing. It doesn't seem to bother any of my other fish. Sooo I think I will never buy fish from high salinity areas in the future. RJ >> for a $4.99 fish they sure are pleasant to look at. Oh well when these go >> that's it. It might be a salinity issue.

Sooo I think I will never buy fish > from high salinity areas in the future. I am not saying lower salinity is causing blindness. I am saying the lower salinity is against keeping animals in conditions close to their natural ones... The difference between 1.025 and 1.029 is not that great, but the difference between 1.029 and 1.019 is quite something. It is definitelly not optimal condition for any reef animal. Instead of lowering salinity as an ich prevention, maybe you should keep some cleaner shrimps which eat parasites of the fish skin and gills in a natural way. Ich is not deadly for a strong fish which is otherwise well fed and well cared for... |
