thank you Pete for your great (as always!) information which I read very carefully. I agree with you that the problem seems to be a mixed infection and, unfortunately, very virulent. I cannot understand where it came from because we have definately not had any heat spikes…
We decided to consult the Munich University (they have a veterinary department for reptiles and fishes) and are working with them on this issue now. We lost another fuscus last night and brought him to the pathology to find out what the name of the game is. They gave us a broad spectrum antibiotika which we administer in the hospital tank (there are 6 fuscus which are treated) every second day after a water change of 70-80% for 8 days. On Monday we should get the results and know (hopefully) which parasites and/or bacteria are involved. I will let you know.
We are starting a new tank for the Reidis (which are all healthy) and I am thinking of re-doing the Fuscus tank also.
I am trying to understand why all the Fuscus got ill but the Reidis did not. I have bred Maine coon cats for a while and learned a lot about genetics. The Fuscus we have are from parents which are siblings – I do not know how long the inbreeding goes on already. Couldn’t immunsupression be a problem with inbred fishes/seahorses also?? Just wondering…
Thank you for your help and have a great day.
