Fish Data : Jaguar Cichlid or Managuense Cichlid, Managua Cichlid, Jaguar Guapote, Aztec Cichlid

   These is a large fish, semi-aggressive and beautiful cichlid that is a popular and fun companion for the more experienced fishkeeper. Unlike most cichlids the Jaguar doesn't present a permenant patterning until it has fully matured, and its visuals will change as it ages. For instance, while younger Jaguars display prominent vertical black bars, the adults tend to lose these bars and replace them with the eponymous "Jaguar" patterning.

   In addition to the name Jaguar Cichlid, these fish are also commonly known by other descriptive names such as Jaguar Guapote, Guapote Tigre, Spotted Guapote, and Tiger Guapote. Other common names are derived from their scientific name, such as Managuense Cichlid and Managua Cichlid, and still others describe the fishes' place of origin, such as Aztec Cichlid.

   In the wild these fish will reach up to two feet (24" or 63 cm) and can weigh up to about 3 1/2 pounds. Fortunately, they are much smaller in the aquarium, only reaching about 16" (40 cm). Due to their large size and semi-aggressive temperment, they are a great fish for a huge system of large South and Central American fish but should not be kept with smaller or less aggressive fish. Use dark gravel to bring out their light purple base color.

   These fish is moderately easy to care for as long as they have a large tank and appropriate tank mates. They are predators and will eat smaller fish and invertebrates. Many do not tolerate any other fish in their tank unless they are a male/female pair or if the aquarium is sufficently large enough (200 gallons or larger). Even then the male may attack and kill a newly introduced female. They become more aggressive when they are in breeding mode and should either be isolated to their own tank or all other fish should be removed at that time.

   Jaquar Cichlid will dig in the substrate, so provide a bottom of coarse gravel with some rocks and wood for places to hide. They will also need a large rock for spawning. Don't include plants as they will be torn apart. Be sure you also have a tight fitting lid as they will jump out at times.

Difficulties in keeping

   Jaguar cichlid care isn’t difficult, if the necessity of having a big tank and powerful filters isn’t considered a a problem. Of course, this fish isn’t for beginners. It’s very large, aggressive and it’s a raptorial feeder.

Feeding

  These cichlid is a raptorial feeder.The fish feeds on everything that moves and that it can put into its mouth. It can be fed with small feeder fishes. During one meal one mature jaguar cichlid can consume up to 10 mature swordtails.

  Jaquar  cichlid can be fed with large blood worms, earthworms, prawns, large insects, small reptiles, frog larvas, meat farce, big flakes of dry feed, even mause or big goldfish. The fish should have one meal in a day and it’s possible to make one day in a week a hunger day.

Care and keeping in a tank

   Tank size should be large, at least 100 gallons capacity. Jaguar cichlids are very aggressive and to decrease their aggressiveness they need to have their own territory.

    Large objects should be used for the tank design – rocks, snags and big grained gravel should be used as a bottom. There’s no need to put plants into a tank since these monsters will destroy them rather quickly and mercilessly.

    All cichlid fishes are bottom diggers. Jaguar cichlid isn’t an exception, since it also likes to move the rocks around the tank bottom. Its size helps it a lot in this task. The bottom gravel should be cleaned well to prevent constant bottom surface changes and appearance of mud in the water.

  The optimal water temperature for this fish is about 24-26°С. pH should be kept about 7, i.e. the medium reaction should be neutral.

Fish Data : Jack Dempsey Cichlid

    These fish is a large and magnificently colored South American Cichlid. It is stocky and compact in shape but can grow to almost 10 inches (25 cm) in length.

     A mature Jack Dempsey is a beautiful fish, but It it takes over a year for the full coloration and patterning to develop. The adult will have a dark purple-gray background contrasted with iridescent light blue, green, and gold spangle spots all over its body. Male Jack Dempsey's tend to have more of these brilliant spots than females, and also present bright red edges on their dorsal and anal fins. In addition to the baseline coloring, many captive bred color varieties have also been developed and are available today. One of the most notable and exotic is the Electric Blue Jack Dempsey.

    The names of this cichlid, both scientific and common, all have a story. When first introduced to the aquarium hobby this fish was considered quite ferocious, though today it is known there are quite a few other cichlids which are far more aggressive than the Jack Dempsey. However, because of this perceived hyperaggression its common name became "Jack Dempsey" after the 1919 Heavyweight Boxing Champion of the World. Its genus name Rocio was named after the wife of the describing author, Regan, and its Spanish interpretation means "morning dew," an allusion to the sparkling scales on the cheeks and sides.

     This cichlid is a very attractive show type fish. It will do well if provided with adequate space and compatible tank mates. It likes to burrow and have plenty of places to hide, so provide a tank bottom of fine deep sand and use rock and sunken driftwood decoration to form caves and hiding places.In addition, it likes to have a floating cover of live plants to help diffuse direct lighting and to swim among, though it will also tend to pick at and eat any live plants in its tank. Providing it with some lettuce and blanched cucumber can help ameliorate this tendency, however it is still recommended to always keep an eye on the status of any live plants in the tank.

     Although the Jack Dempsey is certainly an aggressive fish, it is not nearly as combative or aggressive as some of the more recently identified cichilds, such as the Red Devil. Theycan be kept singly or in large groups, though if you plan on keeping more than one it is easier and safer to keep them in large groups rather than in pairs. If keeping a pair for breeding purposes, it is recommended they be kept in their own tank. They will not tend to do well with other fish and should either be monitored closely in a community tank of similarly sized and aggressive cichlids or kept in a species specific tank.

Feeding

    This Cichlazoma is a predator, so you should feed is with live feed: brine shrimp, blood worm, tubifex, though thawed and milled seafood will do as well. However, you shouldn’t forget about plant additives – these may be finely chopped lettuce, cabbage or blowball leaves.

Difficulties in keeping

     It’s quite simple to take care of Rocio octofasciata, since it’s not demanding, so it can be kept by the beginners. However, you have to keep in mind that this is an aggressive fish that get’s on well with other cichlid species while it’s young, but as the fish grows it becomes more and more aggressive, so then it’s desirable to keep it without any other tank mates or only with large fishes.

Keeping in a tank

    As a majority of Central America cichlids Rocio octofasciata doesn’t have any special requirements as for the tank conditions. Nevertheless, the tank water should be clean, i.e. with zero level of ammonia and nitrite, and nitrate concentration shouldn’t exceed 40 mg/l.

    Nowadays, all these can be reached by means of strong biofiltration and regular water renew. Rocio octofasciata tank size capacity should start from 100 liters (26,42 gallons) for a couple of adult fish.

    In fact, this species aggressiveness to a large extent depends on the fish tank size. In small tanks (up to 250 liters or 66,04 gallons) an adult couple of Rocio octofasciata, as a rule, can’t stand any tank mates around, unless it be some catfish or very small fish and juveniles.

   In small tanks also there may be fights between the fish male and female. If this happens, you should immediately take the female fish away from the tank.

   Keeping the fish couple for 3-6 month together and then for 1.5-3 month or more apart, is considered to be ok if you keep Jack Dempsey fish couple in a small tank (in a big tank the female fish just swims to its other side and usually the male fish doesn’t chase her).

     Also the fish isolation from each other is a way to decrease the number of their spawning, since doing it too often isn’t healthy for the fish, especially for Jack Dempsey female fish.

     Quite often this species inhabits in rather poor conditions due to their careless owners and seem to show rather high vitality. However, this plainness is rather nominal.

    Young Jack Dempsey fish can actually inhabit in tank water polluted with nitrogen compounds, however, very few of the fish live to the age of 4 years old. Negative influence of toxic substances accumulates and then when the fish becomes an adult it shows in the form of hexamitiasis and other diseases.

Meanwhile, provided with proper care lifespan in a tank is about 7-10 years and more.


    When the water temperature becomes lower than 24°С (75,2 F) the fish tends to stay close to the heater. Therefore, we can consider water temperature 26–27°С (78,8-80,6 F) as optimal one for Rocio octofasciata.
