Would these work together? The tank will be a planted 20g, and we have soft, neutral water. If I get the 75g for Comet, it'll free up the 20g; and I've been wanting my first community for a while now.
Edit: The substrate will most likely be sand.
There are few species that can be acclimated to the low end water density of the fiddler crab (1.005). Oddly most mollies and guppies, along with American flag fish. And given the crab's ability to live in fresh water temporarily, I could keep them together initially in fresh water and over time add salt water with each water change until the density is brought up.
There is just so much info to take in and so many options. X3
Not odd at all. All these fish live in coastal areas and can move back and forth between fresh and brackish freely. Guppies have even been acclimated to full sea water strength in the past with no negative effects.
They don't get wide at all. They're probably some of the narrowest fish around. They stay even thinner than bichirs. However, remember that snakes can fit things in their mouths that are wider than they are soooo . . . anyway, just don't put the farlowella with it.
Oh god no. Just worried about the female krib, she'll be the smallest thing in there. I'll have an awesome cave going so hopefully she'll defend herself. And the baby synos too.
Snakes can only open their mouths that wide because the bottom of their jaw disconnects.. Like if you have no bone in the middle of your chin. Hope ropefish don't have that. I read that they're thought to be closely related to amphibians.
