[chercm]

what is the difference between the sand goby and the rest of the gobies ?

[chercm]

is my sand suitable for the goby ?

[Qxnviolet]

Hrmz, i think the grain of your sand is abit too big for gobies. Maybe if you get those larger species.... What grade is your substrate anyway?

[colinsoon]

looks like grade 2 or 3 to me...

sand-sifting goby

but with the grain size of your sand, those gobies will die eating -LOL- all swallow death. grade 0 or 1 only suitable.

what's your problem? you sand bed getting dirty? for that size of your sand, you should perform sand bed cleaning\vacuming regularly.

IMO:

you can try add-in (few) new powerhead(s) to help blowing across the sand bed, to reduce garbage stacked up there.

oh, i read some threads at RC on relevant topic, ppl concern that gobies spill the sand crazyly, covering their coral.

generally watchman goby like the diamond is the recommended one, as it sift\filter the sand be right back at where it suck them.

yellow head will make a big mess, if you dont mind.

you can readjust your powerhead to have move power\flow over the problematic spot.

Or new small-power\flow flow should help.

but noted such approach doesn't mean you don't need to maintain the sand bed. You still need, but can be less frequent, and minimize the working spots to other more flows-stagnant areas.

me personally, i would gradually replace the sand, and get a long-time sand-sifter to work for me. 1 stone 2 birds

an another way may be to dose the anti-PO4 or more carbon running to ease the bad chemical build-up (not my preference). But these only should be practice by ppl with more confident.

Marine tank is like a small mini-chemistry lab, play-play with it and your livestocks may "mutate"..... hehehehee....

how big is the sand shifter?

sand shifting sea stars get pretty big so not recommended.

best to get an algae blenny. although not a sand shifter, it does look for food in the sand.

the two spot is commonly seen in the lfs.

shrimps gobies also do a good job of shifting through the sandbed, especially if paired with a pistol shrimp. but be careful, the digging into the sandbed might cause some rocks to fall if not stacked properly. if you added sand then rock during initial setup, you may have some problems with the digging.

is my sand too big for the goby ?

[Skipper32]

i had a star in eachof my tanks to handle such problems like excess "remains" or waste laying on e sand bed.....so far so gd....got them for abt $3 - $4 each, depend on size.....got a bigger one for my 3ft...

[jacobus]

bro .. u only have 1 twin spot goby ? they need to be in pairs leh ... from what i heard ... they are one of the hardest sand sifters to keep.. keep before a pair ... one of them kena attack by by annoying boxer shrimp and died ... the other one slowly wasted away ... IMO u should try a blue cheek goby aka golden head sleeper goby. mine sifts all the time and is not a shy fish .. very interesting to watch ... should consider tt if u happen to have any more space for sand sifter ..

[Qxnviolet]

Nah, no problem being alone...it harressed the partner i got for it to death. Its terribly hardworking, thats the problem...digging holes around my corals and burying them....hah. BTw, its fine being alone for the past few mths...so guess dun have to be in pairs...

[chercm]

where got sell the star ?

i went to AM but they do not have

[KennethK]
