Question

for eels and some other fish

and whats ur opinion on best overall substrate ?

freshwater

Answer 1

When I use substrate and all, I prefer a fine gravel in most every case. Very, very rarely do I use sand due to the increased cleaning hassle. Of course, I will use it is it will make a real difference to the fish.

Answer 2

Hi, I have no experience with sand but on best overall substrate I would say avoid anything like coarse, pea-sized gravel that could get stuck in their mouths. Anything smooth is fine, especially the small 3mm type often called 'Roman' or Dorset' gravel & it comes in a choice of many colours. Another good choice is larger pond-safe polished river rocks or pebbles available from many garden centres.

Answer 3

Even though food particles and fish excrement will show up better on the sand, it is harder to clean and maintain. I would prefer gravel because it is easier to vacuum than sand. Sand can also clog up a filter if it gets stuck in there.

Answer 4

My favorite is a natural colored very fine gravel. It's almost sand like though it is actully larger. You can use this for all varieties of fish as well as plants.
