Description:

Betta Macrostoma is a rarer species of Betta in the aquarium trade. They are expensive, and hardcore betta-enthusiasts will keep and breed these fish. Fry will need acces to warm air to develop labyrinth organ. These fish often inhabit slow-moving water along rivers and streams. These fish live in shallow water. These fish have an interesting courtship. The male will aproach the female with mouth agape and fins showing. Females often direct their flank towards the male, and will gape and flare in response. Males will often eat eggs. Males grow much bigger. They grow larger in captivity.

Found rarely in commercial stores.
Sooo beautiful!

Gymogeophagus Terrapurpurra

32537730-B2DD-4082-AC25-C2CA8ECF5869.jpeg

One of my most dominant gymnogeophagus terrapurpurra

Size: 4"
pH: acidic and neutral are best. Will tolerate quite a range.
Tank size (in gallons): 30g minimum. Recommend 40 breeder or more.
Country of origin: Uruguay
Diet: zooplankton, microinverters in the wild. flakes and pellets in captivity
Temperament: best in pairs.
Nitrate: <30ppm
Salinity: N/A
Fished for: No
Status: Not Evaluated, but suspected Least Concern
Harmful to humans: Harmless

Description:

These fish will tolerate most water parameters. They were discovered in 2016. They are spread throughout Uruguay in many different areas. These fish like yearly drops in temperature. During the winter, this species will eat very little. They are best kept in tanks with a layer of sand, and many plants including topwater plants such as Water Hyacinth and Duckweed. A unique behavior done by juvies is spitting sand at one anothers face. They are best kept in groups for when they are small, and seperated into pairs later on. Almost all Gymnogeophagus Terrapurpurra sold are of the 'Rio San Juan' variety. These fish can go in waters 50 degrees and under, and up to 85 degrees or more.

These fish can be found in fresh, brackish, and salt water! Males often Wrestle with each other. Weaker males will immediately back away. In nature, locals use them as fighting fish in place of Siamese Fighting Fish.
