Is it safe to hide the heater in a plastic tube on the inlet flow ?

Malawi tank, so little or no plants (unfortunately)

There is still a modest assortment of plants possible with mbuna. Just
have the plants in there first, protect the roots (ie: Amazon Swords)
or have water column feeders (Pennywort, Hornwort), and try bad tasting
plants (Onion bulbs) or less destructable plants (ie: Anubius) and
introduce the fish as juveniles.

I was going to use plants, but my idea of "little or no plants" means
only a light covering, ie where you can still see the back of the tank
!! My idea of a planted tank is where you have to hunt the fish !!

I got a good list from Tropica's site. You can choose fish-proof plants
to suit low light conditions. I was going to try some in there.

The best reason to try something is sometimes because someone says it's
impossible ;~)

Thanx as ever
