i have a problem, i setup a 75gallon aquarium last dec 2006 w/ 4 clown fish, 4 blue yellow tail damsel and a wrasse.. suddenly yesterday may 20, 2008
1 wrasse, 3 clown fish, 2 yellow tail damsel died one by one up to right now as i got home from work... they started dying yesterday when i also got home from work.
and as i checked my water params, i was shocked salinity level is at 1.04 ? is that whats causing their death ? all my fish are 1 year old above and i bought them really small and now they have grown up and i was really sad seeing them dead realizing i bought them babies and i successfully raised them to how big they were right now and just die one by one
can someone give me advice right away what to do ?
all is left are 2 yelllow tail damsel a clown fish
i don't have corals or anemone by the way just the fish and live rocks and some small crabs i think there were 6-8 w/c i just remember all started dying too w/ the other fish
and i just noticed right now, one of the remaining blue w/ yellow tail damsel has a huge white spot on it's body, chalk like white and has an almost red spot on the center, what is that ? he seems to be still strong and alive
Your salinity level is high should be about 1.022 -->1.024, did you add anything to the tank recently, what are your water paremeters?(amonia,nitrite,nitrate,ph), I would start off with a 15% - 20% water change and get the salinity to carect specs.
just an update the blue yellow tail damsel just died.. now i only have 3 left 2 clowns and a damsel no signs of what i saw on the damsel that just died so far
You are in a predicament, to say the least.
You are required to remove buckets and buckets of water, replacing the water with fresh water, unsalted. This will adjust the salt levels to be within an acceptable range (1.022 - 1.025, some keepers steady it at 1.026 though). This adjustment will need to be done relatively slowly, the fish are already extremely stressed and further duress could break them entirely. Pace yourself when adding the freshwater or the salinity flux could be the last finishing blow.
Time is critical, get to work my friend or there will be a lot more dead fish where those came from.
question ? what caused that white chalk like thing that grew on my damsel's belly ? when i got him out of the tank minutes after he died saw the middle part of that white thing like it was bitten by something ?
Have you decided on how your salinity became so high?
It appears to me that you have been using salt water to replace evaporated water. Did you realize that salt does not evaporate? Evaporation replacement should occur with freshwater. You might occassionally replace evaporation with saltwater to account for "salt creep", but this would be rare.
