knight gobys

[adamj]

the brackish is up with live plants, mangrove root looking decorations, and knight gobys.

any thoughts on the husbandry of these little guys?

also, we need to get this brackish area going, not many posts here

My biggest challenge with the knight gobies was their picky eating habits. It was just too difficult to deal with the live brine shrimp (much less blackworms) and they wouldn't go for any of the flake.

Here's a link to another spot that my shed some insight:

Cool man thanks! Any info is of cource welcome. Im happy to say mine are eating completely fine, They really enjoy tropical flake, lucky for me lol. but thats what they had been used to eating for ages at the lfs, im slowly going to introduce them to other live foods.

No probs...try doing a google search on "knight goby breeding" or "knight gobi breeding" and see what you find.

i'ts been a couple weeks now. the tank is cycling out fine. the gobys are doing EXTREMELY well. I've been watching the fish and the cycle closely as to make sure the gobys can handle the cycle. They are eating great, even eating flake. They seem to LOVE it. I've got a small two gallon setup with line brine i feed them every so often. Some of the plants i tried didnt take to the salt so i had to pull them, but i've gott a java fern thats doing well and the mondo grass appears to be fine, but im watching it closely.

Im thinking of adding 2 mollies. any thoughts?

Where did you get mangroves? I can't find them locally or online

 

[adamj]

well, the mangrove isnt real. Its a mangrove sstump decoration. HOWEVER! im setting up a 20 long that'll be a half and half brackish for crabs. I plant on getting some live mangroves for that.. www.liveaquaria.com has the mangroves.

[lordhappy]

Well, in a really small tank, those bananna plants can sure look mangrove-ish

 

[adamj]

on the topic of knight gobies, how do u sex them? i have had one in my tank for 4 months, and recently added another one, i want to be able to breed them but i dont know if they are opposite sex or not

 

[adamj]

hi lai liu ha,
http://www.petresources.net/fish/misscel/sti_sad.html

thats a nice little page with pics of a male and female, it can be harder to tell the sex when the gobys are young but as they get older, the blue color in the males fin stands out allot more.

hello

yes thats the first site i came across while searching the web about sexing them, except that in that picture its obvious, but in the pet store, none looked like the bottom picture haha

 

[adamj]

i imagine the ones at the pet store are younger. Give them time. Also, i imagine the tank at the petshop their at isnt brackish. That could have something to do with it. I've also noticed that in males, when stressed, they will loose some colour, but when calm and setup in a permanent tank, they will show the colour again.

k thx

have u had any luck breeding before? i read that the young need rotifers to eat, but i dont even know what those are...little tiny worms or something?

 

[adamj]

I've not bred them yet, but the tank conditions i have setup for them are ideal for breeding so ill see what happens. They are cave breeders as well, they spawn on cave ceilings

rotifers are microscopic aquatic inverts.

 

[Lai Liu Ha]

so far my gobies arent getting it on...at least i cant see any egg sacs

i still dont even know if they are opposite sex!?

 

[adamj]

how big are they? might take some time for them to show signs of sexual differences. females = less blue on dorsal fins, larger bellies, darker in color ( i think ) males = slimmer, taller dorsal fins, more blue, lighter.

 

[Lai Liu Ha]

they are about an inch and a half, the blue colors on the fins look really similar, and they both look to be the same shape as far as i can tell
