The Pseudanthias flavoguttatus, or red saddled anthias, is a pink to purplish marine fish with a yellowish head and a distinctive row of red saddles along its back. This species is known for its vibrant colors, peaceful nature, and compatibility with reef tanks. They are deep-water fish that prefer dim lighting and should be fed a carnivore diet of meaty foods multiple times a day.
Appearance
Color: Pink to purplish body with a yellowish head.
Saddles: A row of red saddles or bars with pale areas along its back, ending in a large red blotch on the upper caudal peduncle.
Male features: Males have an elongated third dorsal-fin spine and a yellowish tinge to their anal fin.
Size: Can grow up to 4.5 inches (about 11 cm).
Behavior and temperament
Temperament: Peaceful and active, with a disinterest in corals or invertebrates.
Social structure: They are schooling fish and are best kept in groups, though they can live in pairs or smaller groups.
Social dynamics: They are hermaphroditic, meaning the largest female in a group may turn into a male if the existing male dies.
Aquarium care
Tank size: A minimum of 70-80 gallons is recommended, ideally larger for groups.
Diet: A carnivore that requires frequent feedings (several times a day) of meaty foods such as frozen brine or mysis shrimp.
Lighting: Prefer low to moderate lighting as they are deep-water species.
Aquascaping: Should be provided with plenty of live rock for hiding, as well as open areas for swimming.
Compatibility: Reef safe and peaceful, but should not be mixed with other anthias species.
Experience level: Considered difficult to care for and not suitable for beginners, often requiring professional experience
The Lactoria cornuta, or longhorn cowfish, is a marine fish easily identified by two long horns on its head and two spines under its tail, resembling a cow or bull. It has a hard, box-like body with a rigid, bony carapace instead of scales, and its skin can release a toxic substance when it is stressed. This omnivorous fish is yellow to olive in color, often with white or blue spots, and lives in the Indo-Pacific region.

Other characteristics
Diet: Feeds on zooplankton and planktonic crustaceans in its natural habitat. In captivity, they will accept flakes, pellets, and meaty foods.
Reproduction: Oviparous (egg-laying) and protandric hermaphrodites, meaning they are born male and change to female as they age
Entacmaea quadricolor е вид морска анемона, известна още като "балонна анемона" или "четирицветна анемона", която е силно желана за соленоводни аквариуми заради живите си цветове и способността си да развива балоновидни накрайници на пипалата си при интензивно осветление. "Електриково зеленият" вариант се отличава с ярък, блестящ зелен цвят на пипалата, които могат да достигнат до 12 инча (30 см) в диаметър при идеални условия. Тези анемони се грижат за симбиотична връзка с рибите-клоун, които намират защита в техните жилещи пипала, а в замяна ги защитават от хищници и им помагат да се захранват.
Общо описание
Окраска:
Има ярки, наситени зелени пипала, които блестят и се люлеят в аквариума.
Размер:
Може да достигне до 30 см (12 инча) в диаметър, но в аквариум обикновено остава по-компактен.
Признаци:
Под силно осветление развива отличителни балоновидни накрайници на пипалата, които се смаляват и придобиват по-удължена форма при недохранване или недостатъчна светлина.
Поведение и екология
Симбиотична връзка:
Известен е със симбиотичната си връзка с различни видове риби-клоун.
Хранене:
Храни се с малки риби, планктон и други морски организми, които улавя с жилещите си пипала. Препоръчва се допълнително хранене с парченца месо от скариди, крил или други ситни риби.
Грижа и поддръжка
Светлина:
Изисква интензивно осветление, за да развие характерните балоновидни накрайници.
Хранене:
Препоръчва се директно хранене поне веднъж седмично.
Особености:
The Orangeback fairy-wrasse (Cirrhilabrus aurantidorsalis) is a small, colorful fish known for its vibrant orange back, which contrasts with a magenta stripe along its body and a shimmering belly.

The ATI Essentials Mixed Reef set 2x2.7 L is a two-part, ultra-concentrated liquid supplement for mixed reef aquariums that supplies major and trace elements to promote coral growth, coloration, and health. It simplifies aquarium maintenance by providing a ready-to-use, highly concentrated solution that doesn't require mixing, with a simple equal dosage for both parts. The formula includes elements like calcium, magnesium, and alkalinity, as well as essential trace elements, and is optimized to help reduce nitrates and phosphates in tanks with higher fish loads.
Key features
Two-part liquid system:
The set includes two 2.7 L bottles containing essential major and trace elements for your aquarium.
Highly concentrated:
The formula is approximately 5 times more concentrated than traditional Balling solutions, making the 5.4 L set space-saving.
Ready to use:
No mixing or preparation is required, saving time and effort.
Simple dosing:
Both parts of the solution are dosed in equal amounts, which can be adjusted based on the aquarium's specific needs for alkalinity and calcium consumption.
Comprehensive elements:
It provides a complete supply of major elements like calcium, magnesium, and alkalinity, plus trace elements like iodine, iron, and zinc, without causing unwanted accumulation.
Nutrient reduction:
The included "KH Complex" contains organic KH sources that help reduce nitrates and phosphates, making it ideal for mixed reefs with higher fish stocking.
Stabilizes parameters:
Helps stabilize water chemistry, which promotes better coral growth, metabolism, and coloration.
Low-temperature crystallization:
At low temperatures, crystals may form in the bottle. You can dissolve them by warming the bottle in a warm water bath. If operating at cold temperatures, it's recommended to dilute both solutions 1:1 with RO water.
Live marine copepods are small, naturally occurring aquatic crustaceans that serve as a highly nutritious, live food source for various marine fish, including difficult-to-feed species like mandarin fish and seahorses, as well as fish larvae. They are rich in essential nutrients, high-quality fats, and proteins, which support growth, enhance pigmentation, and improve disease resistance in fish. In addition to being a primary food source, copepods also contribute to a healthy aquarium by helping to cycle nutrients and consume algae and detritus, functioning as a natural clean-up crew.
Benefits of Feeding Live Copepods to Marine Fish
Superior Nutrition:Copepods provide essential proteins, omega-3 and omega-6 fatty acids, and other vital nutrients that promote the health and development of marine fish, especially young fish and fry.
Natural Feeding Behavior:Their natural movement triggers a feeding response in fish, mimicking natural foraging behaviors and making them an ideal food for picky or challenging species like mandarins.
Enhanced Fish Health:The high nutrient content and live nature of copepods can improve a fish's immune system, increase resistance to disease, and reduce stress.
Improved Pigmentation and Growth:Feeding copepods can lead to better coloration in fish and improve their overall growth rates and survival rates.
Aquarium Benefits:Beyond being food, copepods are an active part of the marine ecosystem. They graze on algae and consume detritus, helping to keep the aquarium clean and cycle nutrients.
Suitable SpeciesLive marine copepods are particularly beneficial for:
Difficult-to-Feed Species:Mandarin fish, pipefish, and seahorses.
Fish Larvae and Fry:Their small size and high nutrition make them perfect for young fish and newly hatched larvae.
Corals and Filter Feeders:Copepods and their eggs are also consumed by corals and other filter-feeding organisms.
How to Use and Introduce Copepods
Add to the Aquarium:Introduce bags of live copepods into your aquarium to allow them to reproduce and establish a population.
Utilize Refugiums:Adding copepods to a refugium can create a self-sustaining food source and benefit the larger display tank.
Regular Introduction:Consistently adding copepods helps ensure a continuous supply of live food for your fish and other tank inhabitants.
