I kept mine on fine gravel that was 2-3mm diameter. They were fine with it.I just read that some of my fish, the Peacock gudgeons, prefer sand.
Any info about sand substrate would be helpful.
Sand holds nutrients? Please explain how so compared ro gravel.IMHO, sand > gravel substrate....gravel holds detritus, sand holds nutrients...gravel has to be deep-vacuumed, which can be a PITA...with sand, just swirl and siphon the surface of the bed
And you don't have to buy pricey "aquarium" sand, either
I use this in 2 of my tanks, around $6 for a 50# bag...inexpensive, inert, looks great, no pre-cleaning necessary, and grows plants just fine
Quikrete 50 lb. Pool Filter Sand is a properly graded and dried sand. It is designed to be used in swimming pool filtration systems. This pool filter sand also features a tan color.www.homedepot.com
Plain natural brown gravel that we bought from a company called Cook Industrial Minerals in Jandakot. We bought it from them and bagged it up at the shop to sell to customers.
Oooo, thanks @Colin_T !Plain natural brown gravel that we bought from a company called Cook Industrial Minerals in Jandakot. We bought it from them and bagged it up at the shop to sell to customers.
There are a number of different gudgeons with the peacocks being the smallest. I had those and in different tanks I had Mogurnda mogurnda. They are mostly from Australia and New Guinea.
Gudgeons lay eggs in a cave (I used pvc pipe and half ceramic flower pots on their side) and the males usually look after the eggs.
