Water Conditions for Mamela Lemon Jake

They fall under standard Malawi water conditions. pH of about 7.8-8.8 and the temp should be around 80 degrees.

What are your current water conditions ?

As with most other fish, weekly water changes are recommended. At the least every other week.

 

here's a little info that'll help...



Care and feeding:
The African Butterfly Peacock is one of the most carnivorous of the cichlids. In the wild they feed on zooplankton, specifically larvae and will also eat crustaceans. Provide them with a meaty diet; pellets, frozen and freeze-dried daphnia, bloodworms and brine shrimp are excellent choices. Avoid tubifex worms as they contribute to a disease called "Malawi bloat." You can also use shrimp mixes (the European Shrimp Mix is cheaper than prepared foods and just as nutritious). Feed once a day when young and 5 to 6 times a week when adults unless they are breeding. Avoid the desire to feed this fish more often than it needs, as this will keep the water quality higher over a longer time.
A 55 gallon aquarium is okay for these fish, but 75 gallons is suggested. They do fine in either freshwater or brackish freshwater but need good water movement along with very strong and efficient filtration. Provide open space for swimming and a lot of caves to which to hide, sleep, or breed. They prefer subdued lighting.
Malawi Cichlids will deteriorate under poor water conditions. As these are messy fish, do water changes of 20 to 50% a week depending on bio load. Malawi bloat is a typical disease, along with other diseases that ail all freshwater fish.

Water Region: Top, Middle, Bottom:
These fish will swim in the bottom and middle areas of the aquarium.

Acceptable Water Conditions:
Crushed coral can help keep the PH up. However a higher PH means that ammonia is more lethal, so water changes are a must for these fish.
Hardness: 6 - 10 ° dH
Ph: 7.7 to 8.6
Temp: 73 - 82 ° F (23 - 28 ° C)

Social Behaviors:
The African Butterfly Peacock is best kept alone in a small tank, or as a group of one male and 4 - 6 females in a large tank. They are peaceful toward those of the same species as long as it is not 2 males, unless tank is very large and can support different territories. The African Butterfly Peacock will tolerate those of a different genus as long as they are peaceful, similarly sized, though different in shape. They will get along with all other Peacock Cichlids of the same genus.
This fish is best kept with other medium sized Malawi cichlids that are not overly aggressive. Aggressive Mbunas are not good tank mates for the African Butterfly Peacock.

Sexual Differences:
Males are more colorful with the back part of their dorsal and anal fins being longer and sharper. Females are drabber in color with rounded anal and dorsal fins.

Breeding/Reproduction:
The African Butterfly Peacock has been bred in captivity. They reach sexual maturity around 4", which is 1/2 the adult size. Keep 4 - 6 females with one male for the best breeding success. The male will display an intense coloration to attract the females.
All Cichlid parents tend to their young, making them easy to breed. They should have their own breeding tank as a couple guarding their babies can be a force to reckon with and this aggression is acted out on other tank mates. A 55 to 75 gallon tank is suggested.
It is difficult to witness a spawning of African Butterfly Peacock because it is done secretly in a cave. They are mouthbrooders. This is where the females will lay their eggs and then pick them up in their mouths, after which, they pick at the male's anal fin to get him to produce "milt" or sperm. The female will then take this milt into her mouth and the eggs are fertilized at that time. She will carry them in her mouth until the fry are old enough to be able to feed on their own. This takes around 21 days and the size of the clutch is up to 50 eggs. She will nibble and eat next to nothing during this time

 

Looks fine to me.

 

I don't think fungus would be present on a fish and not be visible for that long. If they came with it you would have seen it pretty quickly.

I would suggest using PimaFix and MelaFix in the tank. That will take care of both fungal and bacterial infections as well as the cloudy eye issue.
