In Sahrmann et al. 80% of the participants gave positive answers to an open question about their experience in the exhibition. Adverse reactions to participants were not reported in any of the studies, but Sahrmann et al. stated that 7% of participants indicated that they were nervous, anxious or insecure when touching the animals. Like the two investigations by Cracknell et al. photos used in a laboratory, it food for saltwater fish was unlikely that side effects would occur for participants and there were no animal welfare problems. If you follow these simple tips, your fish will live a happy and healthy life! A replacement of the filter system or new installations for your tank? Make sure you are there when it is time to eat so that all work does not go unnoticed; otherwise your little friends may not be as lively as they could be.
Finally, the response rate was quite low (32.83%), so it is not clear whether the included participants were representative of the source population. To evaluate selective results reporting, the method portion of the studies included was compared with the results presented to identify any discrepancies and determine whether an adequate description of the results was given. Since no studies have been conducted according to a published or registered protocol, it was not possible to make comparisons between study protocols and published results. In addition, since there was a lot of heterogeneity in the study results, it was not possible to assess publication bias with funnel plots as this is not recommended for use in the results evaluated in less than ten studies .
Several studies yielded anecdotal reports that participants responded positively to interventions, but none collected and reported this data rigorously and systematically. The findings of the intervention studies were largely inconclusive. Unlike research with other animals, such as dogs and cats (for meta-analysis, see Ein et al. ), there was little evidence that visa-based interventions help reduce stress or psychological and physiological anxiety. Promisingly, one of the highly weighted and two middleweight studies found significant positive effects on results related to physiological stress and anxiety or related results . However, two studies found only partial support and three studies found no significant effects .
Rub the sides of the tank and use a gravel vacuum cleaner to clean the gravel at the bottom. Finally, put everything back in the tank and add enough new water to fill the rest of the tank. Water flows in nature, such as in rivers and streams, so that the waste is washed away or the volume is much larger than that of a household aquarium, such as in ponds and lakes.
A previous assessment addressed this problem, but the narrative report focused on research from a restorative environment perspective and did not use a systematic approach. Consequently, relevant evidence for current research questions was excluded, while the systematic approach used in the current evaluation led to a more complete picture of the research results. Although studies of each design were included, the assessment of the risk of bias and the robustness of the evidence ensured that the research results were considered under methodological limitations. Two studies evaluated whether the presence or contemplation of an aquarium could reduce heart rate and blood pressure in people undergoing medical procedures, and none of the studies found a significant effect on any of the variables (one study reported no heart rate findings ).
Even if you use an aquarium filter, it is still important to clean your aquarium by hand. Each fish has its own lighting requirements, so it is important to examine how much and what type of light your pet fish needs. Lighting also depends on the size of the tank and the needs of each living plant in the tank. Ensuring that the tank water parameters are correct is also essential for healthy and happy fish. Confirmation that the water is correctly conditioned at the correct pH value and at an appropriate temperature is key. By checking the filters regularly, the water remains clean and safe for fish.
