?What kinda cat is this?
- Thread starter Filthy Sanchez
- Start date
Are they readily available at LFSs? What size do they attain and what's their temprament, diet, etc.?
I've never seen them at any lfs. Several of our sponsors get them in periodically. Fugupuff has kept them for quite awhile. I'm sure he has some good insight on their captive care requirements.
Polynemus paradiseus Linnaeus, 1758
Family: Polynemidae (Threadfins)
Point map Order: Perciformes (perch-likes)
Class: Actinopterygii (ray-finned fishes)
FishBase name: Paradise threadfin
Max. size: 23.0 cm TL (male/unsexed; Ref. 3479)
Environment: demersal; amphidromous (Ref. 51243); freshwater; brackish; marine; depth range - 25 m
Climate: tropical
Importance: fisheries: commercial
Resilience: High, minimum population doubling time less than 15 months(Preliminary K or Fecundity.)
Distribution: Gazetteer Indo-Pacific: Pakistan to the west coast of India and Sri Lanka. Elsewhere, in the Bay of Bengal. Reported from Viet Nam (Ref. 9706). Probably occurs in Malaysia (Ref. 5756) and Laos (Ref. 9497).
Morphology: Dorsal spines (total): 7 - 7; Dorsal soft rays (total): 14 ? 15; Anal spines: 2; Anal soft rays: 11 ? 13
Biology: Lives over sandy bottoms, regularly entering freshwaters during breeding season. Feeds mainly on crustaceans (especially shrimps), small fishes and benthic organisms.
Red List Status: Not in IUCN Red List (Ref. 53964)
Dangerous: harmless
Polynemus paradiseus
Common Names: Paradise Threadfin
Synonyms:
Polynemus aureus
Polynemus hilleri
Polynemus longifilis
Polynemus risua
Polynemus toposui
Family: Polynemidae
Distribution: Indo Pacific; Indo-Pacific
Main Ecosystem: Sandy Marine; This fish is not an obligate marine fish.
Temperament: Active; This fish will never stop swimming!
Diet: Carnivore; This fish will feed on small invertebrates, especially shrimps, and may feed on small fish.
Care: Though brackish, it is euryhaline (can live in a wide range of salinity) and therefore can be kept in freshwater. It can be a finicky eater, but not moreso than other finicky eaters on the market that are more common.
An active swimmer, it prefers water movement and high oxygenation. Some even say the fish must continue swimming or it will die, using ram techniques for respiration like sharks. Also, the fish feels stressed confined in small spaces, of course being able to feel it with its feelers.
pH: 7.0 - 8.5
Temperature:24C - 30C (75F - 86F)
Hardness:10 - 20 dH
Potential Size: Male: 23cm (9.1"); Female: 23cm (9.1")
Water Region: All; This fish will just swim all over the tank.
Gender: Unknown.
Breeding: Unknown, though it will migrate to freshwater environments to reproduce.
Main Colours: Silver, Blue, Grey
Markings: No Markings
Mouth: Normal
Tail: Forked

I've only seen those guys once at a pet shop. I don't remember how much they were asking, but I'm sure it was a grip
