Hey, new member here!
So I have a spare tank just begging for something epic. its a 70g tall bowfront that I got for a song from a local seller (some elbow grease was required...)
I'm inspired to use the height of the tank (around 24" or 60cm) to my advantage. The idea is to create pillars like from the Zhangjiajie mountain range in China rising from the canopy below, capped with vegetation. I'm also in love with the idea of floating/suspended rocks (yes, avatar)
But I'm unsure how to make the pillars. I've gone on a couple expeditions to beaches to look for rocks but they are never the right proportions, and a certain level of detail is needed to convince the eye of the scale. I dont know what type of rock to look for either or how to go about hunting a specific rock type.
I came across carving styrofoam - which appears to have the best level of detail and realism - but in the end it's painted styrofoam so I worry about durability - one chip and there's a bright pink spot in your tank!
Carving Foam Rocks
And then there's cement, which would be the most durable but I fear wont achieve the level of detail and realism required.
I'm also thinking about glueing/cementing rocks together to create the pillars and some tactical moss growing to hide the seems. this looks like a promising avenue if I can find a good source of rocks.
