Goby With 2 Problems

I thought he looked under weight but wasnt sure never seen one of those fish before.
Being thin when still eating can be internal parasites to fish tb.
 
wut about krill? :unsure: ill overfeed him now :D


No, you don't want to overfeed him just as much as you don't want to underfeed him- you need to do more research and find out exactly what you should be feeding him and how much/often.

I have posted to you before a couple of weeks back on how your goby was starving, which you denied at the time. Howeever, although you have been seriously underfeeding the goby, it will starve just as much if you don't feed it the right foods.

More importantly though, are you keeping him in a freshwater, brackish or marine tank? What is the temp in the tank? It looks like you are keeping it in freshwater, which is really bad for them;

I hate to say it, but your goby looks in a seriously bad way, it may be too late if its stopped eating completely (often a sign of doom when a starving fish stops eating).
Try getting hold of some frozen bloodworms, the krill should be fine too, but if you feed dried foods make sure you soak them before hand so they sink and are eaiser for the goby to find- not all dried foods sink though, so frozen foods are best.
 
Gobioides species such as this are filter feeders which require tiny live and frozen foods like daphnia and brine shrimp to survive, they cannot manage larger foods like krill.
 
CFC is right, up to a point, but these fish do not filter water but mud. In the wild, they take in mouthfuls of soft mud and remove any small invertebrates they find. In captivity, bloodworms and other such foods will be readily taken this way. They learn how to filter feed water in captivity, capturing daphnia and brine shrimp in a very comical way, but to what extent this is natural behaviour I do not know.

You appear to have a sandy substrate, which is excellent. Above all else, you have to understand that they have virtually no eyesight, and they feed primarily at night. They cannot compete with loaches, catfish, and so on. You need to provide the right foods at nighttime, and let the fish feed without other fish trying to steal its dinner.

One thing often forgotten is that these fish also eat algae. Those little teeth they have are for rasping algae (and presumably small animals) off rocks, sort of like how plecs or mbuna feed. It's a good idea to give them algae pellets at night, of the type formulated for plecs. These will fall apart and the goby will eat up the fragments.

Starvation is the #1 cause of death for these fish in captivity, I am reliably informed.

They can live, just about, in freshwater but really need brackish water at least SG 1.005, and ideally around 1.010. If you fish is in freshwater, you will improve your odds of success dramatically by getting some marine salt mix and over a couple of hours doing water changes to raise the SG of the aquarium to around 1.003-1.005. Over the next few weeks, raise the SG to 1.005-1.010, as preferred, keeping an eye on the filter. Obviously salt-intolerant fish and plants will need to be removed.

tokis, 1. i wuz kidding about overfeeding.2. that was my avatar.3 he is in a brackish tank. im not that irresponsable. i have no other food for him, just krill and flakes and newt pellets, he is going to eat flakes or krill cuz walmart dosent have any bloodworms and my parents wont allow me to go to petco at the time. if he dosent eat there is nothing i can do.

ps: thanks for the heads up neale ive got some algea pellets and will serve him them tonight
 
Good luck with the fish. If you can't get to the pet store to get bloodworms in the near future, you have some options at the grocery store. Best of all are bags of frozen shrimp. These are very good value. Get the small cooking ones. Asian food markets often have these in bulk. Grind them up with your fingers, so that the goby can sift out the little pieces at night. Your fish wants bits of food about a quarter the size of your little fingernail, no larger.

Other options would be small bits of chopped fish, squid, clam, and mussel.

These gobies also like chopped earthworms, if you don't mind doing that!

Cheers,

seriously i would go with what wilder said and do some meds! ive been having some problems with my fish these days and let me say hes been a total life saver!!!

:rolleyes: except that wilder knows little to nothing about Dragon Gobies (as she freely admitted earlier).

listen to nmonks, he's our resident brackish fish expert.
