hi! i was wondering how common is it for oscars to dig into sand? i also want to have have plants with him, so any ideas for the plants?
Yes, it will work. You can superglue epiphytes on rock or driftwood and anchoing roots will develop over time. Cichlid like to dig on the substrate level and tend to ignore objects high up. Anubias, Java fern and bolbitis have tough leaves and bitter taste that even herbivores will ignore.Attach plants to driftwood with cable ties. Anubias and java fern work well for this. Tough, thick leafed plants will work well. Delicate fragile or stringy plants will be shredded, and all will likely be uprooted.
