Dragon Violet Goby

[pandacichlid]

hello,

I do believe there are numerous types of Dragon Violet Goby

one being: Gobioides broussonenti; another being Gobioides peruanus

please inform me on the differences with pictures and all that?
abit confused haha

thanks

It appears they are very similar fish with the main difference being distribution. Below are from fishbase:

Gobioides peruanus

Gobiodes broussonnetii

The differences between the two are not great, but the easiest is colouration: G. broussonnetii has stronger purple chevron-like bands on the body, while these markings on G. peruanus are much less obvious, basically short bars spanning the lateral line, strongest by the head, weaker towards the tail. There are some nice pictures in the Aqualog book of the two species.

Maximum size, care, diet, etc. are similar, so identifying them doesn't really matter.

Cheers, Neale

I searched for them by scientific name and wondered why I was getting the same fish haha but now I know silly me.
That advice was great, thanks
now I want to know which is freshwater and which is brackish; I know there's a debate to if they're actually brackish, fresh, marine. I've heard they can live happily in fresh or brackish, but can also eventually live in marine

thank you!

Neither is a true freshwater fish. Keep both in low-end brackish. Regardless of the fact they may live in freshwater in the wild, the balance of experience with these fish *in captivity* seems to be that they live longer and stay healthier when kept in brackish water. This isn't uncommon among brackish water fish -- see figure 8s, mollies, bumblebee gobies, and knight gobies for examples of fish that *should* do well in freshwater, but often don't.

that's a good point! I think I may donate him to my girlfriend, because my cichlids seem to be abit aware of him all that time and I don't want to keep him if he's going to do better in brackish conditions.
