thinking about light brackish

[krichardson]

I think big sailfin mollies would work and not be eaten

I think a hungry moray prowling about in the middle of the night would tear a molly apart.

The bumblebee,mollies and glassfish would get eaten.

I must of misunderstood the post. I thought OP was just asking what brackish fish wouldn't outgrow a 55 gallon, not what would be compatible with a moray. Also, I never meant for all these fish to be kept together..it was just a list of small brackish fish. Thanks for the clarification

Oh you're welcome,the OP went on to say that he already has a moray and intends to bring in a violet goby and a toadfish.

thanks for the input. I agree adult sailfins maybe ok. As for as Chromides really depends which we are talking about

most eels dont stay at brackish u know, also the toadfish will need saltwater when it gets older and is poisonousness as hell. And they make a hell of a noise... srs u dont want to keep that tank near ur bed.

(at 14 seconds and u will hear this the whole night long at some periods)


I would go for a saltwater tank if u wane keep eels and toadfish. Also dragongoby's in the shop are freshwater and not brackish. They won't last Long in brackish unless u get wild caught ones

You have any credible references for the dragon/violet goby being truly fw? I have yet to come across that in any of my reading

it depends on the grower. But if it's kept in freshwater since a few generations before it's a freshwater fish. U have to ask the grower or the shop. It's not always freshwater, it is indeed mostly brackish but some are freshwater.
I tried to find the source but its quitte some time ago that I read this.

)
I wanted to do a brackishwater tank with dragon goby, green puffer and bumblebee but I was told that the dragon goby are mostly freshwater. I think it was on the dutchpufferforum.
But the toadfish and murene are saltwater fish when they are full-grown.

The drago. Gobies most commonly available are brackish water fish

Playing with the idea of doing a light brackish 55g. What fish can I do that won't out grow this tank?

My aquarium is currently at 1.009sg so it qualify at light mid brackish

However, it is all locally-caught small morays for now.. Uropterygius Micropterus, Echidna Rhodochilus all topped at 30/40cm, and both are true brackish species. There is a G. Polyuranodon a brackish to FW species, for now it's 20cm, this species is said to grow to 80cm, but most does not grow that much. And there is also an E. Nebulosa, a mostly marine eel which are now about 15cm (max length at about 40cm, still rather small), we captured it in a brackish river at 1.014sg, so I decided to keep it here for awhile until we can rehouse it to an SW tank. If it shows any signs of stress I will immediately return it to the river where we found it.

Interestingly I found an article which says that E. Nebulosa prefer brackish water in the wild, even though the writer also recommend pure SW (I agree with the writer though).

Wild fish go to changing salinities to get their salt needs, in a aquarium the water tends to stay at a more constant salinity.
