Things to note when picking Fish Tank Decorations and Accessories

1. Aquarium Size

Decorations are beautiful but stuffing your tank with these is ugly. Over-stacked decorations limit space for fish movement.

Better to have one creative addition appreciated by the fish.

It’s more advisable to decorate your aquarium based on the theme in mind. Choosing accessories by themes like treasure wrecks or mermaid themes makes decoration decisions easier.

2.      Height of Aquarium Decorations

Like the real seas, aquatic habitats are divided into upper, middle and lower regions. Fish spend a good time in any of these regions, so leave good space for movement in each.

To effectively distribute space, one or two tall additions that reach the upper region  (based on aquarium size) and a few short ones of about an inch or two at the bottom are okay.

Your fish will adapt better if fish tank decorations align with a kind of pattern.

3. Fish Colour

If the feel of your aquarium is a concern, you can use the colour of your fish as the focal point.

Aquarium designs and decorations either counter or go well with fish colour. If your fish is light-shaded and doesn’t have a strong colour, dull-coloured decorations are okay with them.

Your fish colour should pop against decorations and background.

Generally, your decorations and accessories choice gives the aquarium its theme.

For a natural-themed effect in the fish tank, green plants add good colouring, and gravel and pebbles also complement that.

4. Fish Agility?

Agile and active fish use more oxygen than less active breeds. If you have such fish, accessories like oxygen-producing bubble makers help to provide needed air to maintain an active and healthy fish.

Final Thoughts on Creative Fish Tank Decorations and Accessories

Most Fish tank decorations and accessories like gravel have sharp sides. These are not good for your fish as they can scratch off their scales, and cause wounds that may eventually be infected.

When you’re choosing accessories for your aquarium, ensure that you avoid any that have sharp edges, allowing you to create an attractive aesthetic without risking your fish’s safety.

Remember not to overdo it by stuffing your fish tank with decorations. Just pick a theme, a few aesthetic decorations are okay.
