Changes in feeding frequency or amount may be indicative of a problem such as inappropriate feeding, inappropriate environmental conditions, or disease (see Section B). Action should be taken to rule out or resolve any environmental stressors and to identify any disease issues.

Feeding can be encouraged by using food that is of the highest quality, appropriate for the species, of a size that can be processed by the individuals, and fed at appropriate times of day. This is easily confirmed if other members of the species are readily consuming the diet. Changing the feed items or delivery method may encourage feeding. This can include changing from pole feeding to toss feeding and/or changing where in the system or water column food is offered. If social stressors are a factor (e.g. tank‐mate displacement), isolating individuals for directed feedings can be helpful.
