Feeding science
Most tropical fish eat 2-3% of body weight per day — goldfish slightly less (2%), bettas slightly more (5%, two small meals). Feed only what fish consume in 2-3 minutes; uneaten food fouls the water.
| Fish type | % body weight / day | Feeds / day |
|---|---|---|
| Tropical community | 2-3% | 1-2 |
| Goldfish | 2% | 1-2 |
| Betta | 4-5% | 2 (small) |
| Cichlids | 2-2.5% | 1-2 |
