30 gallon aquarium with 2 mollies platies otocinclus and 3 red minor tetras all about full grown how many neon could you get?

Given the tank size (30 gallons) and the existing fish population (2 mollies, several platies, otocinclus, and 3 red minor tetras), it would be appropriate to add approximately 6-8 neon tetras to the aquarium.

Adding this small group of neon tetras will provide visual interest without overcrowding the tank, ensuring that there is enough swimming space and resources for all fish inhabitants.

Remember to gradually introduce the new neon tetras to the tank to minimize stress on all aquarium residents.
