Re: Which one better light for Red
1. 27, with water height around 1.5 m as long as you use all the available space for aros. If you use some of the space for filtration than you have to reduce the number of aros.
2. As long as the plant can live in 28-29C it's should be ok. Ps. Fighting will still occur even when you feed your aros properly. Some fishes will try to become a local king.
3. You can use pond filter.
