how much damage can a sleeper goby cause?

[WRASSER]

hippo,

i am not going to buy another 150gal. tank t make a refug. my thought was the wrasse are always picking at the sand bed and LR, so i don't know if the infauma (haha) will run out.
i have had the mandarin for about three weeks, and he is always picking at the LR. i would say a constant pick at it, i try to see if it is eating spectrum, sometimes it looks like it but i can't say for sure.



thank you,


wrasser 8)

Good luck. watch your mandarin closely, if you see it's abdomen caving in, you may need to isolate it and provide very nutritious live food to recondition it back.

Most mandarin in captivity died from starvation.

The wrasse situation I feel is not so much their feeding, but them liking to become buried at night. I used to have 8 or so wrasses in my 120 that all buried themselves at night. Some would even go all the way to the glass bottom under 5 inches of sand. And yes, a dragon wrasse was one of these 8 wrasses I owned.

i used to have an orange spotted watchman, that was constantly
siftin throught the sand for critters. he really kept the sand clean.
a few months ago, i moved him into my fish only tank since he was getting so big and digging huge burrows. since then, the amount of
life in my sandbed has exploded. worms, burrowing pods of some kind, small brittles. tracks all over the sand.
i really like the sand sifting gobies, they are fun to watch, but they really do take alot of life out of the sand. i didnt used to think so.

I keep a Valenccia puellaris who constantly turns over the top 0.5" of sand in my tank. I have 4" of sand. Below where he works I have vast quantities of worms, bugs, whatever. The only time he goes deeper than 0.5" is when he is working on his two burrows. He doesn't go to the back of the tank or under rocks so I would guess that there are lots of critters back there as well. I was told a DSB was for denitrification, and it is doing exactly that, even with the goby.
