Redfin/tail shark.....

Will a Redfin/tail shark eat bumble bee gobies??

 

[boxman]

Bumblebee gobies are brackish fish - some suggest some will be ok if they are captive bred in freshwater but I wouldnt recommend this as they are naturally brackish.

For this reason I would say not to consider putting them together.

 

[Jo and Gra]

even if the goby are the FW variety?

ok......

so i put them together........

will the red shark eat the goby?

 

[The-Wolf]

I doubt it.
rtbs/rainbow sharks etc are not predators
they are just mean fish when it comes to defending their territory

You would have to be a little careful as BBG do not grow very large (topping out at around 1.5" to 2") bu then they are more than tough enough to not be bothered by a shark (mine front up to puffers and only just lose in the aggression factor but still stand their ground). As The_Wolf said, they aren't predatory, just territorial.

I wish to re-iterate that there is no such thing as a FW bumblebee goby. They are a brackish fish. They will be brought up in freshwater because they (like most brackish fish) spawn up river in freshwater and travel down to brackish as they grow.

Now there is a species of bumblebee goby (Hypogymnogobius xanthozona) which can live out its adult life in hard alkaline water but will naturally live in a low end brakish setup (around 1.005 SG)

The other species (Brachygobius doriae) needs to be in an SG of around 1.005 once adult. I am not saying that the husbandry advice is wrong, it's just I've noticed a trend from people saying that one species of BBG can be kept in freshwater to them being described as a freshwater fish.

Identification of the two species is a moot point and I am yet to find a definitive answer. People will talk about the dark bands being joined up on H. xanthozona but I am not convinced.

i guess if they are in the normal FW setion at the LFS then they will be ok?
they are in with other fish at the LFS too....

 

[The-Wolf]

i guess if they are in the normal FW setion at the LFS then they will be ok?

then you'd guess wrongly
brackish may live for a while in freshwater
but they will not live long or thrive in it.

IME, redtail sharks generally attack fish with similar coloration/body shape as them.....i've seen him chase a rosy barb and paradise fish especially oftne due to the orange/red coloration in each
