Abstract The purpose of the present study was to investigate and compare the karyotypes of three species of Puntius viz. Puntius sarana (Hamilton, 1822), Puntius sophore (Hamilton, 1822) and Puntius ticto (Hamilton, 1822) belonging to family Cyprinidae in terms of chromosomal architecture, banding pattern and number of chromosomes from aquatic ecosystems of Haryana, India. Diploid chromosome no. 50 was observed in all 3 species of Puntius. The chromosomes of 3 species of Puntius showed constitutive heterochromatin at telomeric and centromeric regions of chromosomes.The Ag-NOR (Argyrophilic-Nucleolus Organizer Region) bands were observed on homologous chromosome pair nos. 2, 8 and 14 in P. sophore, pair nos. 2, 9 and 14 in P. ticto. The diploid chromosome number in P. sarana was found to be 2n = 50, 2 pairs of metacentric chromosomes, 3 pairs of subtelocentric and 20 pairs of acrocentric chromosomes. Chromosomal studies on the P. sophore revealed the diploid chromosome number to be 2n = 50, showed 16 pairs of metacentric chromosomes, 5 pairs of submetacentric, 2 pairs of subtelocentric and 2 pairs of acrocentric chromosomes. The diploid chromosome number in P. ticto was found to be 2n = 50, with 15 pairs of metacentric chromosomes, 6 pairs of submetacentric, 2 pairs of subtelocentric and 2 pairs of acrocentric chromosomes. No heteromorphic sex chromosomes were cytologically detected. Variations in chromosomes are observed with respect to earlier studies which may be due to variation in habitat conditions as a result of anthropogenic activities.

РЕЗЮМЕ. Мета цього дослідження полягала у вивченні та порівнянні каріотипів трьох видів Puntius viz. Puntius sarana (Hamilton, 1822), Puntius sophore (Hamilton, 1822) і Puntius ticto (Hamilton, 1822), які належать до сімейства Cyprinidae у плані хромосомної структури, смугастої покресленості та кількості хромосом з водних екосистем у штаті Хар’яна, Індія. Диплоїдну кількість хромосом, 50, спостерігали у всіх трьох видах Puntius. Хромосоми трьох видів Puntius показали наявність конститутивного гетерохроматина у теломерах і центромерах хромосом. Ag-NOR (аргентофільний ядерцеутворюючий регіон) бенди спостерігали на гомологічних парах хромосом №№ 2, 8 та 14 у P. sophore, парах №№ 2, 9 і 14 в P. ticto. Було виявлено, що диплоїдна кількість хромосом у P. sarana становить 2n = 50, при цьому є 2 пари метацентричних хромосом, 3 пари субтелоцентричних і 20 пар акроцентричних хромосом. Дослідження хромосом P. sophore показало, що диплоїдна кількість хромосом становить 2n = 50, було виявлено 16 пар метацентричних хромосом, 5 пар субметацентричних, 2 пари субтелоцентричних і 2 пари акроцентричних хромосом. Було встановлено, що диплоїдна кількість хромосом у P. ticto становить 2n = 50, при цьому є 15 пар метацентричних хромосом, 6 пар субметацентричних, 2 пари субтелоцентричних і 2 пари акроцентричних хромосом. Цитологічний аналіз не виявив гетероморфні статеві хромосоми. Спостерігали зміни у хромосомах порівняно з попередніми дослідженнями, що може бути викликано зміною умов середовища існування внаслідок антропогенної діяльності.

Ключові слова: хромосома, Puntius sarana, Puntius sophore, Puntius ticto, каріотип

These are some photos I just took using my mobile phone of my 3 year old #CheckeredBarbs that I think are again about to spawn anytime soon in my planted tank. I have successfully bred them once in the same tank without even taking out the parents and succeeded on having several babies come out alive. The trick was to have a lush carpeting plant for the eggs to hatch and the babies to hide and thrive in pristine waters. They are also great for nano tanks since they don’t grow more for more than an inch (some neon tetras are even larger than them) and are also peaceful community tank fishes and can hold their own against larger barbs like Tiger Barbs, Rosy Barbs and Odessa Barbs. Overlooked by most aquarium hobbyists for other more colorful tetras and barbs, but I think nothing beats their personality, aside from the fact that they have good temperament, they graze on green hair algae, detritus and they are not picky eaters. Originally rom Sumatra, Indonesia… they are also commonly known as #CheckerBarb or #CheckerboardBarb #OliotiusOligolepis #Puntius #PuntiusOligolepis #PlantedAquarium #Aquarium #PlantedTank (at The Mondejar Studio)

Understand the Essential Facts on CHERRY BARBS Before Keeping Them

Cherry barbs originated from Sri Lanka but these days they are found in Colombia and Mexico also. As they live in the calm waters, they can easily adjust themselves in aquariums and tanks.

They are basically middle tank fish meaning they love to stay in the middle level of the aquarium. They will rarely come to the surface of the water but sometimes they can make a trip to the bottom of the aquarium, searching for food and places to hide.

They are freshwater fish and are comfortable in moderate conditions of water. You should avoid making sudden changes in the temperature of water because it will harm them. You should also take care while changing the water of the aquarium because a sudden change in the water chemistry can put them under stress.

Like any other barb species, the females are bigger in size than the males. However the males will be more colorful. The combination of various shades of cherry red color will be prominent on the males. The females will be in dull colors, especially orange and yellow.

In the open nature, cherry barbs will not spawn frequently but in aquariums they will be very fast! During the period of spawning, the colors of the males will become brighter. The females will scatter their eggs all around the aquarium. However you should take care to protect these eggs because the males will eat most of them. So if you transfer the eggs to another tank, there is a bigger chance of getting a large number of new ones.

Cherry barbs are very peaceful in nature but there are some exceptions. At the time of spawning, the male becomes very aggressive. Also, if you keep the only a few of them in the aquarium, they will develop stress and become aggressive. So it is advisable to keep them in good ratio of three females per male. The normal size of their group should be about 10.

During the breeding season, the male will constantly follow the female and will try to keep away the other males. The females can lay about 300 eggs every day.

Normally, cherry barbs are not comfortable with other species of fish but if you keep them with the bottom feeding fish like Loaches it can make a better combination. The Loaches are normally shy by nature and like to hide all the time but in the presence of cherry barbs, they will become more playful and both of them can make a good community in your aquarium.

Never make the mistake of keeping other species of fish with the cherry barbs. Even if you plan to keep tiger barbs with them, it is not advisable. Tiger barbs are aggressive species and they will attack and nip the cherry barbs. Angelfish are beautiful and usually peaceful but if you keep them with cherry barbs, there will start looking at cherry barbs as their tasty food!

Cherry barbs are fine with the normal fish food like flakes. They like live food such as brine shrimp or blood-worms as well. However, you should occasionally feed them with green vegetables like lettuce or spinach for proper nourishment.

If you take proper care of cherry barbs, they will grow up to 2 1/2 inches and live up to five years. You should provide them an aquarium with a heavy plantation because it is useful both for keeping their health as well as for their breeding.
