Understanding Both Species of Fish
Getting to know the species better and their requirements will help us narrow down if they are good tank mates for each other. By understanding what each fish needs will ultimately help
Commonly referred to as the Siamese fighting fish, bettas are beautiful specimens from the Gourami family. Bettas come in a wide variety of attractive colors ranging from red to white, with many different patterns and fin types. They grow to an adult size of 3 to 4 inches and the fins of the betta fish can sometimes be double to size of their body. The betta can live for 2 to 4 years and are notorious for their territorial and aggressive nature. An individual male betta should have a minimum sized tank of 5 gallons, whereas female bettas should have a minimum of 10 gallons. When keeping bettas with other fish, you want to ensure the tank sized is increased according to the number of tank mates you want to add.
The Harlequin Rasbora
This colorful fish is a beloved tropical fish that should be kept in shoals of at least 6 fish. A gender ratio of 2 males and 4 females will balance out any chasing for mates. Rasboras are strictly freshwater fish which makes them ideal to be kept with bettas as both fish have similar water condition requirements. A minimum tank size of 10 gallons will suffice for a small shoal of rasboras. They are not overly aggressive and should not attempt to bother other fish in the same tank. These fish live between 2 to 5 years and grow around 1.5 to 2 inches in size.
Is It True That Rasboras and Betta Can Be Tank Mates?
Yes! It can be done if you get the process of introducing them right. You want to ensure both species of fish are kept in ideal conditions with adequate space. There is no guarantee there will not be any chasing or aggressive behaviors when they are adjusting to being kept together. Bettas who have previously been housed with other fish are more likely to cohabitate well with harlequin rasboras. You will need to closely watch them ensure one is not bullying the other. It is also important to check that the rasboras are not nipping at your betta’s long fins. Only one male betta should be kept with a shoal of rasboras, but females can be kept in sororities with the addition of harlequin rasboras.
Providing the Right Conditions
The tank size should be altered according to the number of rasboras you want to keep with a betta.
Filter: A strong sponge filter is ideal for both species. Remember bettas do not like strong currents and sponge filters release bubbles from the top which aid in surface agitation.
The tank should be fully cycled before you place the fish inside. Make sure that the tank is heated around 75°F to 80°F since they are tropical fish.
