Public aquariums can provide hobbyists with numerous insights that can apply to their home systemsHere in the US, the summer travel season is well underway, and popular attractions all across the nation are swarming with tourists. For those of us enamored with marine life, vacation travel often involves a visit to major public aquariums, where we can spend several quality hours figuratively immersed in the underwater realm. (Turns out most facilities get pretty upset if you try to do this literally!) As a reefkeeper, what I find particularly interesting about visiting public aquariums is not just the enthralling experience they provide while I’m there, but also the information I glean from the exhibits that can be applied to my own systems back home.Here are just a few examples: Aquascaping inspiration The smaller display tanks that are often peripheral to the gazillion-gallon crowd-pleaser tanks in public aquariums can provide excellent insights on how to configure rockwork and other aquascaping features in your home aquarium for optimum aesthetic appeal. Sure, artificial elements (e.g., faux coral inserts, etc.) often stand in for the real thing in these tanks, but it’s easy enough to extrapolate from the design concepts on exhibit. Which fish species might coexist Seeing different fish species or conspecific groups “playing nice” in a public aquarium display tank can be helpful in determining whether they’re likely to get along in a home aquarium. However, you do have to take the size of the exhibit into account because both heterospecific and conspecific aggression tends to become more intensified as tank size diminishes.
