Will giant danios eat smaller fish?

Are zebra danios schooling fish?

Zebra Danios are another tight schooling fish… when they’re given the right tank. Unfortunately, these lively fish often end up in tanks that aren’t suitable for them. That leads to them abandoning their natural behavior. Zebra Danios need a long tank. A long 20-gallon tank is a minimum, even though smaller tanks could theoretically host a school.

What does a panther danio fish look like?

The panther danio is a torpedo-shaped small fish that has translucent fins and iridescent scales. Similar to the moustached danio, the panther danio has snakeskin-like markings across its sides. The panther danio’s scales produce beautiful rainbow hues under a light.

How much light does a zebra danio fish need?

Minimum 12 hours of light in a day is required for the Zebra Danio tank. Try to set a good filtration system in the tank of your fish to wash out the toxic particles and wastes from the fish home.

What are nematodes in danio fish?

Nematodes are simply the roundworms that can infect any organ of Danio fish, especially the digestive system. Nematodes are only a few millimeters in length, and there are different species of nematodes.

What kind of lighting do I need for my zebra danios?

Zebra Danios are diurnal fish, so you can mount a medium voltage lighting on the topmost part of the aquarium. Minimum 12 hours of light in a day is required for the Zebra Danio tank.

How do I know if my fish has bladder disease?

A fish with Swim Bladder Disease would often swim horizontally with its tail higher than its head. Note though that some fish types assume this position naturally so make sure to check the breed of your pet. If they’re supposed to assume a straight position when swimming, then there’s a good chance that Swim Bladder Disease has set in.

Is Pseudocapillaria tomentosa a common nematode of cyprinid fish?

Infections with capillarid nematodes were observed in zebrafish (Danio rerio) kept at several research facilities and in a large carcinogen exposure study previously conducted at Oregon State University. We report a morphologic description that identifies the worm as Pseudocapillaria tomentosa, a common nematode of cyprinid and other fishes.

What are nematodes in fish?

Nematodes, or roundworms, have been found in numerous species of fish. Because they are similar to other worm-like parasites of fish, proper diagnosis is important for effective treatment.

What are nematodes and how dangerous are they?

Nematodes, or roundworms, infect many different species of aquacultured and wild fish. Small numbers of nematodes often occur in healthy fish, but high numbers cause illness or even death.

Do nematodes come out of the intestine?

Although parasitic nematodes can infect almost all organs in a fish, the majority of the currently known species have been described from the intestine. Most nematodes infect fish as adults, but a large proportion of them occur as larval stages.

What is the pathogenesis of nematodes?

Nematodes infect freshwater, marine and brackish water fish species. Pathology normally occurs within the intestines but can affect all organs and substantial damage to the host can occur.

Are fish intermediate hosts of nematodes?

Depending upon the species of fish and the species of nematode, fish may be final hosts (containing adult nematodes) or intermediate hosts (containing larval nematodes). Some species of nematodes that infect fish can be transmitted directly from one fish in the population to another (direct life cycle).

How do nematodes spread from one fish to another?

If the nematode has a DIRECT life cycle (Figure 6), then it does not need an intermediate host and infection can spread directly from one fish to another by ingestion of eggs or larvae.

Can nematodes infect freshwater fish?

They infect freshwater, marine and brackishwater fish species and sometimes cause substantial damage to the host. Although parasitic nematodes can infect almost all organs in a fish, the majority of the currently known species have been described from the intestine.

What is the first record of the Nematode Pseudocapillaria obturans?

On the biology of the nematode Philometra obturans (Prenant, 1886) in the fishpond system of Macha Lake, Czechoslovakia. Folia Parasitologica, 25 (3):231-240; [2 pl. (unpaged)]. Moravec F; Ergens R; Repová R, 1984. First record of the nematode Pseudocapillaria brevispicula (Linstow, 1873) from aquarium fishes.

What is the pathophysiology of capillarid nematodes?

Pathologic lesions associated with the infection ranged from inflammatory changes to aggressive neoplasms of the intestine (i.e., intestinal carcinomas and mixed malignant neoplasms). Capillarid nematodes may have intermediate or paratenic hosts.

How to differentiate adult nematodes in fish?

Likewise, morphological differences are obviously used to diffentiate adult nematodes in fish. The identification of cucullanids is based on the shape and length of the worms, the location of the vulva and the shape of the spicule ( Berland, 1970 ).

Are larval nematodes the first intermediate hosts of fish infection?

The intensity of larval nematodes is suggested to be low in the crustacean which are the first intermediate hosts. However, larger fishes are mostly infected only via the already infected crustaceans or small fishes (Mouritsen et al., 2010).

Do nematodes cause disease in fish?

These nematodes can often cause mild disease in all members of a fish genus and, after colonizing a new host species, they can give rise to much more severe disease. Such a species is A. crassus, a nematode of Japanese eel ( Anguilla japonica ), which causes a mild disease in its original hosts.

What is a parasitic nematode?

Parasitic nematodes constitute one of the earliest known groups of helminths in fishes. They infect freshwater, marine and brackishwater fish species and sometimes cause substantial damage to the host. Although parasitic nematodes can infect almos… More… Don’t need the entire report?
