Once you provide the list, I can help you assess factors like:
* Compatibility: Are the fish peaceful or aggressive? Do they have similar water parameter requirements?
* Size: Will the fish outgrow the tank?
* Diet: Do they have similar dietary needs?
* Tank size: Is the tank large enough to accommodate all the fish comfortably?
* Other factors: Are there any specific needs for any of the fish, such as hiding places or plants?
Let me know the fish species you're thinking about, and I'll be happy to give you feedback.
