Plant pictures
Hopefully, they won't be eaten overnight!
The fish currently keeping these plants company are:-
Herichthys Carpinte
Geophagus Brasiliensis
Heros Severum (Gold Severum)
Pelvicachromis Pulcher
Cichlasoma Meeki
and a Plec of some description.
It is the Severum that I believe may be the problem here as I know that they like munching on greens. The one in this tank, however, is only a baby and should not be able to do too much damage too rapidly. Only time will tell.
I will revisit this in a month's time with a report back. Hopefully, all the plants will be alive, well and taking over the tank by that stage.
