I have seen biotopes in aquariums where fake plants have been used to great effect. They are easier to care for and don't affect water parameters.Geoey;3439701;3439701 said:True biotopes must have :
1. real live plants (from the intended location)
2. wood/rocks from the right country(mopani in a CA or SA biotope big fail!)
3. fish from the right country location( and environment just because they are from the same location/country does not mean they would encounter each other in the same body of water.
4. the substrait needs to be beliveable.
As for the rocks, if they resemble rocks from that biotope, does that not make it believable.
