If I had that tank given to me right now, I would stock it with groups of fish that stay under 5cm as adults, like...
10+ Threadfin Rainbows
10+ Forktail Blue Eye Rainbows
10+ Gertrude Rainbows
10+ Neon Dwarf Rainbows
15+ Sawbwa Barb
15+ Hengel Rasbora
10+ Clown Killifish
10+ Rummynose Tetra
10+ Sterbai Cory (bit bigger than 5cm, but very peaceful)
6+ Zebra Otos
But this is not my tank, its yours!![]()
What is your "must have" fish? Stocking ideas can drive you potty until you know this. Once you know the answer, you then find fish that match the conditions of the "must have" (factors like temp range; amount of water movement; aggression; size etc.)![]()
