Do not be tempted to overstock your aquarium with Rummy-nose Tetra. Their displays of varying colours and patterns make them sorely tempting. This unusual mix of styles makes them stand out as attractive fish.
As omnivores in the wild, they live on a diet consisting of small plant matter, small insects, larvae or eggs. Anything they can fit into their mouth, they will try to eat. Flake and pellet foods are easy ways to get the nutrients they need. Live and frozen foods like bloodworms are a great way to get protein. Though your little Tetras will nibble at your plant, they are unlikely to cause any large amounts of damage. Only give them the amount of food they can eat in two minutes. Rummy-Tetras are peaceful and fantastic community tankmates. They can become stressed by boisterous fish. Avoid large species with mouths big enough to fit Rummy-noses in them. Rummy-noses need to be in groups. In the wild, they apart of large shoals. The smallest group you should have together is six. Otherwise, they will be easier to bully by bigger fish.
Rummy-noses can be sensitive to water quality. So much so that even if your tank stays clean, sometimes diseases are unavoidable. Dropsy and Ich are two of the common diseases. A way to check is by looking at their noses. If the colour is much paler than usual, it can be a sign of illness. When decorating the tank, pick plants that will grow to the mid-levels of the water, as that is where Rummy-noses will spend most of their time. The plants provide shelter from other fish and bright lights when stressed.
Most of a Rummy-noses body is silver, except for their head which is a deep red colour. When attempting to distinguish sexes, it is a difficult task. There is no sure
way to do it by sight, only suggested that the females might have larger bodies. Breeding at home can be as difficult since you may never be sure if you have the right mix of males and females. Warming the tank should trigger spawning. Water quality is important here because, without it, they will not breed. You will also need to plant live vegetation. Females will swim over to leaves and roll over to let the male fertilise the eggs. You will need to remove adult fish from the tank once spawning is complete.
Lovely friendly person to deal with. Look forward to buying more fish and accessories from this store.
