FAQ Livestock

Does Aqua Vision Tech offer a health guarantee on their livestock?

Yes, we offer a 90 day health guarantee on a majority of our freshwater and saltwater fish. If you should happen to lose a new fish during the first 90 days that you have it we will either provide a replacement fish of the same size and species or generate a credit on your account.

90 day health guarantee is not applicable if:

  • You add livestock from an outside source into an aquarium that we are maintaining – This circumvents the biosecurity measures that we have in place to help prevent introducing parasites and infectious diseases into the aquarium.
  • If you do your own shopping – you run the risk of introducing nonquarantined and potentially sick fish into your community.
  • Our records indicate that there are poor feeding habits – which cause stress on the fish and may result in larger fish eating smaller fish.
  • Special order fish may not be guaranteed depending on our experience with successfully maintaining them in an aquarium. The fish featured on our website have a track record of being hardy and acclimate to life in an aquarium easily.

How many fish can I have in my aquarium?

This is perhaps the most frequently asked question, and it is the hardest to answer. There isn’t a hard and fast rule about how many fish can safely exist in a certain size aquarium. We often make recommendations on types of fish and numbers, but the individual fish themselves have the final say on just how many fish can happily live together. In order to maximize the number of fish kept together, we recommend selecting species or family groups that typically dwell at different levels of the aquarium. This maximizes the amount of space the fish use within the aquarium, and minimizes the amount of territorial disputes between fish.

Generally these are the recommended stocking levels for different sized aquariums:

  • Aquariums from 55 to 75 gallons should only house 5-8 saltwater fish, or 12-15 freshwater fish.
  • Aquariums from 110 to 125 gallon should only house 8-10 saltwater fish, or 15-20 freshwater fish.
  • Aquariums from 150 to 200 gallons should only house 15-20 saltwater fish, or 25-30 freshwater fish.

We can make recommendations on what species of fish will interact peacefully in your aquarium to avoid some of the most commonly experienced problems of aggression and loss of livestock.

Can I add more fish into my existing community?

This is perhaps the second most asked question. The answer is, it depends. We take into account the fish which are currently in your aquarium – their size, age, and typical behavior and we can make recommendations on what types of fish may be successfully introduced. This isn’t an exact science, and no two fish are going to behave in the exact same manner. Trying to introduce a single fish into an established community typically isn’t a good idea, as the new comer is going in with a target on his back from every fish in your tank. What we typically recommend is to start a community out at a high threshold number and when the numbers drop over time to a lower threshold number, adding in a multiple of new fish to reestablish the original threshold number. The method helps minimize the amount of stress placed both on the new fish and the existing community. Having an aquarium with a continually changing population of fish will generate very high stress levels and overall poor health in the community.

How do I know if my fish are getting along?

There may be the occasional tiff between fish in any given community, that is their nature. In the natural environment of a coral reef, there are often territorial disputes between fish, which don’t result in much more than causing a fish to move out of a certain area. Within the confines of an aquarium, these territorial disputes can result in severe stress on individual fish and even death, as the fish which is being targeted can’t safely retreat out of the aggressive fishes territory, and is relentlessly harassed. Fish behavior is fairly easy to observe and understand provided you know what to look for. These disputes are typically resolved by removing the aggressive fish – since moving the target of the aggressive behavior will often just result in a new target being selected.

Signs you may have trouble within your community:

  • An individual fish does not feed, or is not allowed to feed.
  • An individual fish does not have the freedom to move about the entire aquarium and is being held in a certain place by another fish.
  • Fish darting into another fishes space and making contact – either by nipping or slapping with tail.
  • Fish swimming in close proximity to each other and maintaining an aggressive posture, or constantly chasing around the aquarium.

Can I add shrimp, crabs, starfish or other invertebrates into my aquarium?

We do not recommend adding invertebrates into an aquarium stocked with fish. While it is possible to have these animals living together it severely limits the number an d kind of fish you can have in the aquarium, as a majority of fish regard most invertebrates as tasty snacks. Another complication invertebrates introduce are limitations on how we can prevent and treat parasites or diseases if they should happen to occur. Most effective treatments for parasites and other diseases are highly toxic to invertebrates.
