Female mate sought for endangered fish

ZSL London Zoo launch urgent appeal

Aquarists at ZSL London Zoo are urgently seeking a female mate for the remaining males of a critically endangered fish species, and have launched a worldwide appeal.

The Mangarahara cichlid is thought to be extinct in the wild after the introduction of dams dried up its habitat - the Mangarahara River in Madagascar.

Two of the only remaining individuals are residing in the zoo's aquarium, and unfortunately both are male.

Using international zoo and aquarium associations, London Zoo aquarium curator, Brian Zimmerman, has been working with colleagues at Zurich Zoo in Switzerland to track down surviving females in zoos across the world.  

Having had no success, the team are now launching an urgent appeal to private aquarium owners, fish collectors and hobbyists to help them find surviving females.

Mr Zimmerman said: "The Mangarahara cichlid is shockingly and devastatingly facing extinction; its wild habitat no longer exists and as far as we can tell, only three males remain of this entire species...

“We are urgently appealing to anyone who owns or knows someone who may own these critically endangered fish, which are silver in colour with an orange-tipped tail, so that we can start a breeding programme here at the Zoo to bring them back from the brink of extinction.”

Practices urged to audit neutering data

News Story 1
 RCVS Knowledge has called on vet practices to audit their post-operative neutering outcomes.

It follows the release of the 2024 NASAN benchmarking report, which collates data from neutering procedures performed on dogs, cats and rabbits.

The benchmarking report enables practices in the UK and Ireland to compare their post-operative outcomes to the national average. This includes the rate of patients lost to follow-up, which in 2024 increased to 23 per cent.

Anyone from the practice can submit the data using a free template. The deadline for next report is February 2026.

Visit the RCVS Knowledge website to complete an audit.

New guidance for antibiotic use in rabbits

New best practice guidance on the responsible use of antibiotics in rabbits has been published by the BSAVA in collaboration with the Rabbit Welfare Association & Fund (RWA&F).

The guidance is free and has been produced to help veterinary practitioners select the most appropriate antibiotic for rabbits. It covers active substance, dose and route of administration all of which are crucial factors when treating rabbits owing to the risk of enterotoxaemia.

For more information and to access the guide, visit the BSAVALibrary.
