With age the marbling disappears and the colours become more intense.Size: max. 9 cmTemperature: 21 - 26 °CLife expectancy: max. 3 monthsFood: primeval crayfish foodTriops longicaudatus (red)is an American crayfish. This species is probably a breeding form of the "normal" Triops longicaudatus. In contrast to these, however, the body shell of Triops longicaudatus (red) is transparent, which is why the animals appear wonderfully red in colour due to the translucent red blood.Quantity: basically about 100 to 250 eggsSize: max. 9 cmTemperature: 21 - 26 °CLife expectancy: max. 3 monthsTriops cancriformis var. Beni Kabuto Ebi (red)The red cultivated form of the European summer crab Triops cancriformis probably comes from Asia and has therefore been given the name "Beni Kabuto Ebi". Keeping and breeding corresponds to the original species.The original form is brown marbled. The red Triops lack the brown colour, which is why they appear red due to their body fluid. However, if you look closely, you can still see the marbling. As juveniles, like all Triops species, they are still quite pale. The strong pinkish-red colour develops only with age.Size: max. 7 cmTemperature: 20 - 25 °CLife expectancy: max. 3 months

Notes
The large Amazonas sword plant is perhaps the most popular plant in the aquarium hobby. Its leaves are 3–6 cm wider than those of the ‘amazonicus’ variety, and the height of up to 60 cm makes this species appear even more dominant. Mature clumps, some with more than 50 leaves, are a striking feature. However, the substrate must be at least 10 cm deep for the root system to develop properly. Combined with Helanthium species (dwarf Echinodorus), beautiful South American underwater landscapes can be created.

Limnophila sessiliflora
CHF 6.50
Limnophila sessiliflora
An easy to grow stem plant, ideal for the background of the aquarium. It is characterized by its beautiful green coloration and rapid growth.Difficulty of growing: easyLight requirements: mediumCO₂ requirements: mediumGrown plant height: up to 60 cmGrowth: fastTemperature: 25-30°CPlacement in aquarium: Third levelOrigin: Asia6 cm cup diameterLimnophila Sessiliflora is an easy to grow stem plant, perfect for the third level of a tank. Native to Asia, the plant is characterized by pinnate leavesof light green color. They grow in groups of 6-9 leaves around the stem. Limnophila sessiliflora looks best incompact groups. Because of its structure, it makes an excellent hiding place for juvenile fish. The advantage of this plant is that it is easy to grow. It requires only moderate light, about 0.5 W/l. However, the plant adapts to the light conditions. In stronger light, the stems become thicker, the green color more bright and the structure more compact. In weaker light, the stems may elongate between the leaf nodes, which affects the appearance of the plant.
It can be successfully grown without CO₂ supply. It grows up to 60 cm tall, which makes it a good choice for planting the third level of the tank. Its intense growth helps the aquarium look quickly overgrown. The growing stems can be cut at any point and then replanted in the substrate. In this way, we can quickly compact the clumps. The prerequisite for rapid growth of this plant is a constant temperature of 25-30°C. Although Limnophila Sessiliflora tolerates short-term temperature fluctuations well, it grows fastest at a constant temperature. Because of its growth rate, additional fertilization of the tank with iron- and potassium-rich fertilizer is recommended.Planting: The plant must be removed from the cup and thoroughly rinsed from the gel under running water. This is best done by placing the plant in a container of lukewarm water. Most of the gel will then fall off by itself. Divide the contents of the cup into 3-4 cm lumps and then place them in the substrate..
ProFlora Cylinder 1200 U - single-use bottle
CHF 78.90
Disposable CO2 bottleThis disposable CO₂bottle supplies your aquarium plants with their main nutrient, carbon dioxide (CO₂). Turn the pressure regulating fitting with internal thread onto the external thread (M10x1) of the supply bottles, and you are ready to go. The pressure bottle should always stand vertically as long as it is in use.Scope of delivery: disposable cylinder, ready-filled with 1.2 kg CO₂, dimensions: approx. 45 × 10 cm, thread M10x1Easy installationIncluding mounted rubber standTÜV-testedTotal height with mounted pressure reducer: 37 cmCO₂ disposable bottle or CO₂ reusable bottle?There are two different types of bottle: Disposable bottles, which are disposed of as well as recycled after emptying, and reusable bottles, which could be refilled again and again. Refilling can be done by pet shops and gas companies. If you live in a region where refilling is problematic, for example, the disposable bottle would be an alternative. If the refilling situation improves, you can convert the disposable pressure reducer into a reusable pressure reducer in 2 minutes by screwing on the adapter (JBL PROFLORA CO2 ADAPT u-m). Aquarists who live on islands, for example, are sometimes not allowed to transport filled reusable bottles on ferries or planes. Disposable bottles are then sometimes allowed! (Please always clarify exactly)The size of the bottle often depends on the cupboard below where the CO₂-supply bottle is placed: a 500 g disposable bottle is only 31 cm high (plus pressure reducer = 37 cm), a 500 g reusable bottle with stand is already 43 cm and a 2000 g bottle 45.5 cm high. In principle, of course, a larger bottle is advantageous because it simply needs to be replaced or refilled less often.
