Fetching species data via /species endpoint: slow response or caching issue?

Hey team,
I’m working on a small educational side project at 247uaefreshers.com where I’m experimenting with public APIs to explore how beginners can use real-world datasets — including biodiversity and ocean-related info.

While testing the FishBase API, I noticed that some /species queries (especially when filtered by common names) are returning much slower than expected — sometimes over 5 seconds. I’ve checked network conditions and retried with different endpoints, and it seems isolated to a few common name queries like Tilapia and Barracuda.

Just wondering:

Is there any known caching on those endpoints?

Would it be better to filter by Genus or Family for performance?

Are there any upcoming changes to rate limits?

Happy to share more if needed — thanks in advance!
