I put 3 tiger barbs after I already had a red hearted tetra in for a week. 2 of the barbs sdied. So I moved all the fish left back into my fully working 29 ghallon. Why did they die?! Also, Should I get gravel instead of like eco complete, mearly because of looks, and replace the filter with an undergravel filter? It's a 10 gallon fully planted tank with substrate.
