Anyone has some pics of ideas for hitching for my ponies. I am using artificial corals in the tank and it seems like that what even more places when they swim around.
You can order linking, plastic colored chains from Amazon; but can be pricey IMO when you can be economic about it!
Thus, other options for In-store or budget planning, sometimes Kahoots/Petsmart/Petco/Dollar Store/Daiso/Walmart may have clearance bird toys (with the applicable plastic chains in various colors) that you can repurpose for your seahorse tank
just make sure to remove anything metal & to check the plastic ingredient (if/when repurposing the plastic chains).
