Green Wolf Eel W/green Spotted Puffer?

[Dave Legacy]

Hi,

Here's the run down. I've recently been working on putting together a 37G Tall (29.5 x 12.5 x 25.5) Oyster Reef themed tank to house a single Green Spotted Puffer. GSPs start off in mid-ranged brackish water and then migrate out into full marine as they reach maturity at about 4" in length.

I've recently become facinated by the Green Wolf Eel (C. subducens) and have been thinking about keeping one. After doing some research I have found that Green Wolf Eels don't require a lot of space because they don't move around and that there has been successful breeding of an adult pair in a 30G tank. This meaning my tank size should suffice in housing 1 adult. I have also found that tankmates are ok as long as they wont fit in the Green Wolf Eels mouth (GSP reaches adult size of 6" and GWE adult size of 18") and that puffers are considered one of the acceptable tankmates.

Here's are my questions:

1. Does anyone have any experience with housing a Green Wolf Eel any species of puffer together? What about behavior towards any type of tankmate?

2. Does anyone know what the growth rate of a Green Wolf Eel is? In what time frame should I expect to see it reach the adult size of 18".

3. I have read on Fishbase.org that the Green Wolf Eel has been seen in brackish water. Does anyone have experience with this? If they are tolerant of brackish water, or spend their juvenille life in brackish that would mean I could combine the 2 fish together right off the bat.

Any insight on this topic would be highly appreciated. If I can pull this off I'll start stacking my oyster reef in ways to form caves for the Green Wolf Eel.

Thanks in Advance,
David

GSP's (t nigrovidis) start out in fresh to water and migrate to light brackish water.

However Green Piuffers (T. Fluvalitis) start in light brackish and go into full salt, if you have T. Nigrovidis, the far more common species (IME) then full marine would kill it.
be sure that you have the right one. http/puffernet.tripod.com/confusion.html

Okay moving on, what is an oyster themed tank? if you have any noncoral invertibrates a Green puffer will eat them, it will also nip the fins and scales on your green wolf eel.

I do not believe that GWE's are anadroumous, heading into water of lower salinity to breed, I do think that should you get say an 8" individual you shouldbe able to keep it in heavy brackish 1.017 for a number of months without serious harm coming to it.

Oyster Reef meaning just a ton of oyster shells scattered around the rubble of coral skeleton and liverock... you know, like an oyster reef.

According to the guys on the puffer forum it seems that GSPs do migrate into full marine as adults. You can check my thread in the brackish forum to see what you think on the subject as well. The Ceylon puffer you're talking about isn't what I'm going to be putting in my tank.
