Food and feeding
Glass catfish will accept flaked foods but a treat of brine shrimp and daphnia should be added to the diet.
Glass catfish are to be found in Sumatra, Borneo and Thailand.
Sexing these fish can be difficult; when mature the females tend to be slightly plumper.
Cases of these fish breeding are very few; often fry are seen in the tank by accident. It is believed that dropping the temperature slightly will induce them to spawn but this has never been proven.
If kept happy and in optimum water conditions they are expected to live for 5-6 years.
Glass catfish do not like bare tanks. Plants must be included in the aquarium to keep them happy and they must be kept in groups. They are a peaceful species that do well in a community tank; they are also prone to be a bit skittish, so hiding places need to be provided.
