Large leathers in small tank?

[Lineatus]

I’ve decided to downsize my reef tank as I’ve become unhappy with my tank and want a change. All my colonies are too large and are stinging and/or shading each other.

I’ve had a TMC micro habitat sitting in my attic for a while and have decided to set it up (3.3gallons/15 litres).

The two corals I want to keep are a large green sinularia and colt coral colonies. It would be a tight fit, but they’d slot in reasonably comfortably. They would however be touching each other and the glass in some places. Would this work out? Would the chemical warfare be too much for such a small tank?

For reference, this is the size of the corals relative to my current 15 gallon.

I would think chemical warfare amongst leather corals is not a likely problem. Consider using activated charcoal for chemical filtration.
