Online Help and Consult Fish Diseases


Now you can get online help or consultation on the problems of your fish and fish diseases.

When you cannot get a disease diagnosis or the necessary service or assistance to solve your problems, you use this tool.

The fish doctor Gerald Bassleer will reply within 24-48hrs after you have send in the completed Questionnaire for Consultation together with a  good quality photograph of the diseased fish(es) and your payment of € 24.50 (see link below).

When no consult or good advice is possible, your payment will be send back= no cure, no pay!

For those that want a specific consultancy to solve problems with many or different fish (as business or private), we have a private CONSULTING SERVICE option (with the option of ZOOM-meeting) at  Patreon: https://www.patreon.com/geraldbassleer
