Platinum Sterlet Acipenser Ruthenus 20cmPlatinum Sterlet Acipenser Ruthenus The smallest sturgeon species, Sterlet are naturally found in large rivers where they can enjoy the cool temperatures and high oxygen levels that they require. Unlike their larger cousins, they don't undertake extensive migrations and tend to dwell in deeper channels feeding on insect larvae, molluscs and other invertebrates. Young fish shelter in shallower water away from large predators. All sterlets in the UK
Platinum Sterlet Acipenser RuthenusThe smallest sturgeon species, Sterlet are naturally found in large rivers where they can enjoy the cool temperatures and high oxygen levels that they require. Unlike their larger cousins, they don't undertake extensive migrations and tend to dwell in deeper channels feeding on insect larvae, molluscs and other invertebrates. Young fish shelter in shallower water away from large predators.
All sterlets in the UK hobby are captive bred but they share the same preference for cool, flowing water with high oxygen levels. They have a shark-like swimming style and are very prone to getting tangled in blanketweed, often with fatal results. This means that a suitable pond needs to be large and uncluttered, with good filtration and strong water movement - conditions that are commonly found in koi ponds. The only snag is that sterlet don't have the same seasonal dietary demands, so they need feeding with a fairly high-protein specialised diet through the winter which may be a conflict with the needs of the koi. Orfe are perhaps the perfect companions for these fish as not only do they share the same water chemistry and temperature preferences, they share a susceptibility to chemicals found in treatments, so always check suitability before use.
Like koi, sterlet prefer hard water and keepers in soft water areas are advised to add buffers to increase KH levels and monitor these alongside the usual parameters such as ammonia and nitrite. As these conditions favour the growth of algae, an ultraviolet clarifier is usually an essential piece of equipment to maintain the clear water that allows you to appreciate your pets.
Currently the status of this species' native wild relatives is critical. As with any pet fish, it's important never to release sterlet into the wild where they can impact their wild kin.
Feeding
Carnivore that requires specialist sinking foods specifically formulated for Sturgeon/Sterlets, that are high in fish meal/shrimp meal protein and easily digestible. If other fish are present in the pond, always feed them their usual food first in order to keep them occupied, then offer the specialist sinking food to the Sterlets. This will help to prevent the other fish from greedily consuming all the Sturgeon/Sterlet food before it reaches the bottom. It is very important to ensure the Sterlets are not being outcompeted at feeding time, and equally important that they receive a specially tailored diet. As Sterlets have short guts with limited capacity, a number of small feeds per day is much more beneficial than one large feed, but do be careful not to overfeed. During the autumn/winter months, Sterlets will continue to feed down to 4 °C and it is important that they continue to receive small amounts of food (even when other fish in the pond aren't feeding) in order to prevent starvation. However, do remove any uneaten food promptly.

My favorite robot vacuum! Works awesome!!
Size: 11S MAX, Size: 11S MAX
Eufy is by far my favorite robot vacuum brand we had one for several years and it did amazing with everything from dust to hair and even rocks didn’t phase it! It is super easy to set up, turn on, the settings are very user friendly and emptying the dust bin is super simple! They are very powerful but also compact and can fit in smaller places so that’s great for us and even when I don’t think there’s much on the floor it always gets full! You honestly can’t beat the price for how great these awesome little vacuums work definitely get your value for your money! I was a little skeptical getting the refurbished or Like-New one but I am super impressed so far! So grateful for tools like this to have around that are great at lending a hand 🤩

Sort of OK Budget model
Size: 11S MAX
I'm giving this model 5 stars because at this price, especially "renewed," it's a great robo vac. It is NOT anywhere near the hands-off level of other machines. It can't map the rooms, bumps its way around fairly successfully, but needs frequent hands on to fix something. In my case, with 2 long-haired cats, the most frequent issue is tangled hair in the roller. The machine stops dead and sends out 4 beep distress sounds for a while, then shuts down. Also, the remote seems to work only in line of sight, so if Eufy is stuck somewhere you can't see, and you were out, to find it you'll have to hunt with your eyes. Nevertheless, if your funds are limited, top choice.
Update: After 6 months of usage, I'm giving it only 3 stars. Problems: 1) if you have long-haired cats (I do) their hair clogs the roller fairly quickly. After a while, no matter how well you clean the hairs out, you have to replace the roller entirely as hair seems to get inside it and cause the machine to stop working entirely. 2) the remote works only if you can see Eufy and it can "see" you. If it gets stuck in some place out of sight, lots of luck finding it. 3) when told to go to home base and recharge, it bumps around for a long time trying to find the way home. Bottom line: Where it vacuums the rug/floor is clean, but it takes a lot of baby sitting. Definitely not first choice unless funds are really tight.
