the ray is fine with it she can still bury herself and blow for food.im sure i was getting those dodgy pockets under the sand.one day my readings are perfect the next day its like my tank is not even cycled.i think the ray must of been digging into these pockets and causing the problems.make sense?
tanks 100g the ray and catfish share with a 19" fire eel and a foot long clown knife
Lovely tank
i love the simplistic design, i personally dont like tank that are filled to the brim with things that arent nessisary...
if they are...like mbuna tanks, then that fair enough.
