New update (2 months later)...
Tank continues to do well, both fish (SDs, 1 small BN pleco, 2 Brochis, several Otos) and plants.
I have very little (I am reluctant to say none, but it appears to be NONE) evidence of damage to the plants due to grazing by SDs.
Plants are doing well, some better than others. I believe at this time plants are not more lush due to factors different than grazing by fish, perhaps more due to the short time since planted, the still 'new tank' status (perhaps not enough nutrients in the sand), or other factors I can't control well such as water parameters. I apply weekly a small amount of liquid fertilizer (Seachem Fluorish), and I am probably due to apply some Seachem Root Tabs again. I do not use CO2.
While things can change anytime for the worse (I have recognized this all along), I am considering this effort of a new planted SD tank a success for now. Time will continue to tell us what is the case.
I attribute the preliminary success to:
- Plant selection
- Silver dollar species (3 spp - altidorsalis, lippincotianus and altidorsalis)
- Prior 'training' or 'learning' of the silver dollars (in 2 separate planted tanks, not including some of the plant species now present)
- Varied diet provided to the fish, even though I only feed 4 days per week (with exception of seaweed near daily in small amounts)
- Providing seaweed near daily and frogbit/duckweed permanently in a floating corral
- Having the fish entertained with social interactions, such that they are not 'iddle' or 'bored'.
I cannot gauge the relative importance of these various factors, as this is a completely un-controlled experiment (if it can be considered so). However, in my own mind, all of this factors have been important, even if I cannot demonstrate so.

asked about my experience having Anubias in planted SD tanks (4 separate tanks) - For whatever reason, I had not attempted to keep Anubias with SDs prior to this present tank, where a single Anubias can be seen near the top center, attached to the wood. It has grown great (flowered once, and now having another incipient flower), and has not been touched by the fish. This is very limited experience but so far quite rewarding.
I am sure there are quite a few other plants that can be had with Metynnis silver dollars. n time, I may try some in this or in another tank.
In another thread related to another planted SD tank, [
New planted community setup] I discuss my views about yet another SD species, the tiger dollars (M. fasciatus). I have preliminarily concluded that this dollars can also be had in planted tanks (see the above referred thread), but they appear to be more keen on eating plants, and may be more herbivorous than the other 3 species. This is however, a very preliminar and not fully supported conclusion.
First photo of the current look of the tank; Second photo shows the dollars engaged on eating nori from the floating corral (in this shot just excited about it!).
I would love to hear your comments and opinions. Cheers!
