MARINE AQUARIUM FREE THEMES FULL
Let your creative imagination run wild and create the kind of colourful, fun, fantasy underwater landscape that’s full of movement and bubbles, just like in a Disney animation. Hardcore aquarists may turn their noses up at this one but done properly they can look really impactful and engage younger fishkeepers and non-fishkeepers alike. Stick to Malawi cichlids as they prefer hard alkaline water and rocky, limestone habitats. Note coral sand and reef rock raises the pH of the water so this style of tank doesn’t suit all types of freshwater fish. Decorate with artificial corals and marine themed ornaments and use vivid blue and yellow cichlids from Lake Malawi to complete the look. Use coral sand on the base to look like that pristine desert island sand and use artificial reef rock to give you that creamy coloured rock structure that makes saltwater tanks stand out. You can make a freshwater tropical aquarium look like a marine tank however by following these few easy steps. Many people want their tank to look marine but either don’t have the budget or dont want the hassle of a full-on saltwater aquarium. Keep lighting and filter flow subdued and either leave plants out entirely or hang some jungle looking artificial plants upside down to replicate the forest canopy.

Get the natural lookįit a black background to the tank, use soft, inert, lime-free sand on the bottom and add more than the usual amount of bogwood pieces. Tannins make the water soft and acidic so by using wood, leaves and blackwater in the aquarium you can make many soft water species feel right at home. The water is stained brown from the tannins released by fallen food and leaves from the forest canopy above and blackwater fish often have striking markings or bright, iridescent colouration so that they can see each other in the gloom. “Blackwater” habitats are common around the world and many of the fish we keep from Cardinal tetras to Pearl gourami to Dwarf cichlids naturally inhabit blackwater in the wild. Flooded forest aquariumįew tanks look more like a natural landscape than one simply decorated with fine sand, wood and with brown, tea-stained water. Here’s some easy to create decor themes to make your tank look spectacular. The most eye-catching and impactful aquatic displays are often the ones that follow a theme.
