Two words for tonight. Epic fail.
I got the sand over the weekend, washed it and put it in the tank. I only used 1.5 bags (out of 3). Stoked. Looked awesome, but a little on the fine side. Tonight I transferred birchy (the big ornate) across from the 4' using a pillow case, he's close to 17" now!! As I suspected he stirred up the sand every time he swims with a bit of force. But worse than that, the fine sand appeared to stick to him and in about 5 minutes he looked like he had been rolled in icing sugar. So I very rapidly siphoned all the sand out, and I'm back to a bare-bottomed tank wondering what I should use for substrate. I didn't even take a pic with the sand in.
I've dumped a heap of stress-coat in to help birchy with his slime coat, he gradually seems to be shedding the sand. Fingers crossed it doesn't stress him too much.
So, suggestions for substrates??
