its_an_obsession;3781196; said:i agree with scat. definitely need to get the temperature up in your tank. i keep all my pikes at around 80 degrees.
i also noticed that your pH is high. any idea what the general hardness and carbonate hardness is? anyone have any thoughts on high pH and high hardness affecting pikes health? ive attributed that to some problems in the past.
I've rasied some very nice pikes in hard, alkaline water so I don't think it is hyper-critical but, I have noticed that in hard water the pikes seem to be much more susceptible to LLE. Certain pikes such as Cr. sp. "Atabapo" seem to develop LLE regardless of what their fed or how well they are maintained. I want to get some of these fish that already have LLE and see what I could do with them if kept in very soft water.
If you think about it, a majority of fish that are known for being extremely likely to develop LLE come from habitats with very soft water; discus, many Crenicichla species, Astronotus sp., Uaru fernandezyepezi, Hoplarchus, etc. I suspect that the high levels of disolved solids in the water irritate the thin membrane of skin that covers the receptor pores along the LE much like a rash. Left unchecked the skin eventually errodes away. Diet may have a little bit to do with it as well as poor water quality but I've seen too many fish that are well taken care of that still develop LLE to place blame solely on these reasons.
When's the last time you saw a Rift Lake Cichlid or a Central American Cichlid with LLE? Rarely if ever! I've seen a few but all were being housed in horrid conditions.
I also firmly believe that many of the issues encountered with breeding these soft water species is also directly related to the hardness of the water.
