Mudpuppies (Necturus maculosus)

Does any one on here keep mudpuppies or water dogs at all as i am getting one on February 11th

any one

I have in the past if you need any advice/pointers.

well mine will not eat i got it a bit earlier than expected. i have 3 goldfish in a 29 gallon aquarium with it that is only half full.

Give it time, they may not feed right off. Keep the light low, give them some hides to get into, and most importantly keep your temperatures low (under 70) and your filtration high. Cool, clean water is key.

ok thank you

Also there was a like circle of jelly floating in the water yesterday idk what it is. I tried to grab it but it slipped from between my fingers.

Probably sloughed its skin. Mud puppies and hellbenders both frequently slough if bothered or put into a new environment.

it still hasnt eaten but he hasnt gotten much thinner

Goldfish are a kind of Carp.

Thiaminase is an enzyme, commonly found in a number of fresh water and saltwater fish and shellfish, which is capable of destroying Thiamine (vitamin B1). It is particularly found in the head and viscera.
* Fish which are reported to contain thiaminase include: all Cyprinidae (carp, rudd, roach, goldfish, tench, minnow etc.), smelt Osmerus spp., loach Misgurnus spp., bullhead Ameiurus spp., bream Abramis brama, herring Clupea harengus, dogfish Squalus spp. also possibly mackerel Scomber scombrus and whiting Gadus merlangus.

Some kinds of fish contain an enzyme called thiaminase, which breaks down Vitamin B1. Garter snakes fed an exclusive diet of these fish — such as some kinds of bait minnows, alewives, and other oily fish — can develop a Vitamin B1 deficiency. Symptoms include a loss of coordination and motor control as well as violent convulsions.
