It will be a nice idea to create such a company devoted to creating Aquarium Fish.
As you are skilled at creating gene-modified zebrafish and other aquarium products, it will be a great thing. But undoubtedly it's challenging.

What I can suggest you regarding this purpose are: -

1. Before starting to think about creating a company using blockchain technology, you should learn about different facts related to blockchain technology. Among different types of crypto coins,  Bitcoin can be very risky. So, research about it.
2. Find someone who knows well about blockchain technology.
3. Maybe you can advertise your offer or publish news for a partner who can help you with this.
4. There are many blockchain certified experts who can help you with this. Try to connect them.

Best of luck.
