Remarks: The three lined Hoplisoma is often confused with the much rarer H. julii, which has many small spots on its body rather than reticulated striations present on the head of the three lined Hoplisoma. Along with these striations, this species also has a black spot at the top of the dorsal fin and a black line along the lateral line that extends from the base of the caudal fin almost all the way to the pectoral fins. In H. julii, this line is more broken and typically stops at the ventral fin. The three lined Hoplisoma is a somewhat small Corydoradinae, breeds readily, has an attractive pattern, and is pretty hardy making it an excellent choice for both the experienced and beginner fish keeper.
Three lined Hoplisoma were previously classified as Corydoras trilineatus, but were reclassified as Hoplisoma trilineatum upon publication of a phylogenomic analysis in 2024 that reclassified many species in the Corydoradinae subfamily.
Corydoradinae are small, peaceful catfish that are active shoalers and will stay near conspecifics, making for a lovely sight. They feed by searching through sand with their barbels, making such a substrate necessary for their long-term health. Gravel substrates tend to be abrasive and damage the barbels, leading to infections and an inability to find food.
While these friendly catfish are willing to swim with other species of Corydoradinae different from their own, this does not provide the same social need as being kept with members of their own species. Because of this, it is highly recommended to keep at least six of each species of Corydoradinae present in the aquarium and only mix species if one has the space to keep at least six of each.
Corydoradinae are often looked at as "scavengers," but they should be treated in a similar fashion as the rest of your fish. They are omnivores and require a mixed diet. Sinking prepared foods are readily accepted, as are frozen and live foods such as brine shrimp, blackworms, and bloodworms.

Will my fish look like the picture?
The majority of fish on our website will NOT look like their photos upon their unboxing. Fish change in appearance depending on many factors, including mood, age, gender, and social status. Fish will naturally lose color during shipping and may appear faded upon arrival. Pictures are used as examples only. Pictures may be of mature fish with full color or juvenile fish without color. We encourage you to research the species as much as possible prior to ordering in order to familiarize yourself with the various appearances they may take on. Many species have females that look drastically different to their male counterparts, and many juveniles will not have as much color (or different colors) as their adult forms. If you have questions about how the fish will look, please review their information and email us if you have any questions.
How do I know which fish can go together in my tank?
Research the product descriptions on our website and use Google search to help decide which fish can go together. PLEASE do your research and email us if you have any questions. Also, we have a very active Facebook group called Imperial Tropicals Fishkeepers where you can learn from knowledgable and experienced fishkeepers.
