Goldfish (Pond Size)
Goldfish are a NORTHERN FRESH WATER FISH which can also survive in tropical areas just as well as it can extremely cold environments. The goldfish (Carassius auratus auratus) was one of the earliest fish to be domesticated, and is still one of the most commonly kept aquarium fish. A relatively small member of the carp family (which also includes the koi carp and the crucian carp), the goldfish is a domesticated version of a dark-gray/olive/brown carp native to east Asia (first domesticated in China) that was introduced to Europe in the late 17th century. The mutation that gave rise to the goldfish is also known from other cyprinid species, such as common carp and tench. Selective breeding over centuries has produced several color variations, some of them far removed from the "golden" color of the originally domesticated fish. There are also different body shapes, fin and eye configurations. Some extreme versions of the goldfish do need to be kept in an aquarium—they are much less hardy than varieties closer to the "wild" original. However, some variations are hardier, such as the Shubunkin. The main varieties are Common Goldfish, Black Moor, Bubble Eye, Celestial Eye Goldfish, Comet-Tailed Goldfish, Fantail, Lionhead, Oranda, Pearlscale, Pompoms, Ryukin, Shubunkins, Demekin, Ranchu, Panda Moor & Veiltail. Ours are somewhere between Common and Fantail -- with large "forked" tails, flowing fins and an array of various colors. Goldfish do a great job cleaning up a tank but they produce a high level of PH so you need either a really good filter and / or constant water changes -- especially if you're going to have these in a tank.

Convict Chichlids (Pond Sized)
The Convict cichlid (Amatitlania nigrofasciata) is a species of fish from the family Cichlidae, native to Central America, also known as the zebra cichlid. Convict cichlids are popular aquarium fish and have also been the subject of numerous studies on fish behaviour. In natural habitats, the species feeds on crustaceans, small fish, insects, various worms, plants and algae. In 2007, the species was moved from the genus Archocentrus to a new genus, Amatitlania based on a study of Archocentus species by Juan Schmitter-Soto. However, a 2008 study led by Oldrich Rican has suggested that all the species in Cryptoheros and Amatitlania, including Amatitlania nigrofasciata, should be moved into the genus Hypsophrys. A number of synonyms exist for this species including: Archocentrus nigrofasciatus, Cichlasoma nigrofasciatum, Cryptoheros nigrofasciatus and Heros nigrofasciatus. Convict cichlids are endemic to the lakes and streams of Central America. In particular, the species occurs along the eastern coast of Central America from Guatemala to Costa Rica, and on the western coast from Honduras to Panama. Convict cichlids prefer moving water, and are most frequently found in habitats with cover in the form of rocks or sunken branches. Convict cichlids are relatively tolerant of cool water, an ability which has allowed the species to colonise volcanic lakes at elevations of 1500 m (4920 feet). At four natural habitats of the convict cichlid in Costa Rica, the pH was found to range from 6.6 - 7.8, while alkalinity ranged from 63 to 77 ppm CaCO3. The daily water temperature ranged from 26-29 °C (79-84 °F). The species also occurs outside its natural range in Australia: in the warm effluent of power stations in Victoria, and in tropical Queensland. In addition to Australia, the species has been introduced to Réunion, Japan, Mexico, and the USA. Convict cichlids are easily maintained and bred in aquariums. The aquarium should be decorated to mimic the natural environment and should include rocks and artificial caves for breeding. The species is an unfussy omnivore and most types of prepared fish foods are readily accepted. The species will also consume aquarium plants. Convict Cichlids are aggressively territorial during breeding and pairs are best kept alone in suitably sized aquariums. It has been suggested that brood care is reduced in aquarium strains. Due to the tendency of the species to dig, external filtration is recommended over undergravel filter systems. The relatively small size of this species, along with ease of keeping and breeding, make the convict an ideal cichlid for beginners and advanced aquarists alike interested in observing pair bonds and brood care in the aquarium. In very large environments, these fish tend to grow rather large, their body and fin structures become more elaborate and their gray-ish color turns into more of a neon purplish-blue. When understanding the psychology of these fish, they can be made to co-exist with things such as guppies, sword tails and other fish that they would normally hunt down and kill. Doing this is not recommended unless you already know what the hell you're doing :)
