Neon tetras need dim lighting, a DH less than one, about 5.5 pH, and a temperature of 75 °F (24 °C) to breed. There also needs to be a lot of tannins in the water. Neon tetras are old enough to breed at 12 weeks. [23] Breeding neon tetras is considered to be difficult in home aquariums. [24]
Dwarf gourami bubble nest made of bubbles, floating plants and plant parts which were torn from a Hydrocotyle by the gourami male. Bubble nests , also called foam nests , are created by some fish and frog species as floating masses of bubbles blown with an oral secretion, saliva bubbles, and occasionally aquatic plants .
While rummy-nose tetras do not need their eggs to be kept in total darkness as is the case for neon and cardinal tetras, the eggs are known to exhibit some degree of photosensitivity, and subdued lighting is highly advisable during egg development in the breeding aquarium.
For breeding, these tetras need water similar to the waters in which they live in the wild; extremely soft water with a pH of about 6 and a temperature of around 77 °F (25 °C). Ideally, the water should be highly stained by the tannins from peat, [3] in subdued light, shaded by plants. It spawns in a school, although in the actual act of ...
The Buenos Aires tetra are very durable, and do not have any special needs or requirements. A maintained freshwater tank and food is all that they really need. However, they are hearty feeders that must be well-fed or they may begin to nip at their long-finned tank-mates. Keeping the tetras in a school of 5 or more definitely decreases aggression.
Bamboo Shrimp need stable water conditions, and they do best in well-established aquariums, like one of the best tropical fish tanks, that have lots of plants and places to hide. 16. Mystery Snails
Unlike other tetras who prefer to live in large shoals, they will also do fine when kept in a group of four or five individuals, making them suitable for smaller aquaria. They still need enough space for the males to stake territories and present themselves to best effort, however. Male black phantom tetra with fins fully extended
The surface and cave forms of the Mexican tetra have proven powerful subjects for scientists studying evolution. [28] When the surface-dwelling ancestors of current cave populations entered the subterranean environment, the change in ecological conditions rendered their phenotype—which included many biological functions dependent on the presence of light—subject to natural selection and ...
