I require concept designs for Tropical Fish Information Card

Industry: Lifestyle/Travel
Kind of design: Template
Target audience: All Ages
Number of slides needed: 10
Data and special elements to include: I require 10 different variations of a design for a tropical fish information card. At this stage, the project is for the front design only.
It will require a custom design background to be created. I have attached sample images for the type of background I'm thinking of. Along with this I need different design concepts for the layout of the card. this includes:
1. Border/No border
2. Different font types
3. Different text positions on the card
Ideas for the visual style: Card size is optional but in proportion to business card size
Things to avoid: Too much colour variation in the background
Preferred colors: blurred blue background with plant
Extra notes: I'm after a very elegant design that doesn't look cheap and too simple.

Only 3 or 4 background designs is required and then use these to create the 10 different layouts.
