Leo_ian Posted September 23, 2020 Share Posted September 23, 2020 I'm planning to do a saltwater paludarium. The tank is about 20gallons. I'll be using a canister filter. Its going to have fiddler crabs in it. I am looking for fish that can live in a small nano or even a pico and live near beaches. Are pacific blue eyes good? Any gobies or blennies that I should consider? Quote Link to comment
sadie Posted September 24, 2020 Share Posted September 24, 2020 I just got a neon blue gobie, I wonder if they would do good in something like that. I bet you could get a few in a 20 gal. He is cute and active. Sometimes he just perches somewhere, and sometimes he is swimming all over the place. I wish I had more then 1. Quote Link to comment
Clown79 Posted September 24, 2020 Share Posted September 24, 2020 How much water do you plan on having in the tank? Quote Link to comment

Haha i have a breeding pair, but they are very expensive in my country $60 per fish. Quote Link to comment

I just found out they are aggressive to their own kind unless they are paired. So I guess I'm sticking with just the 1. I still think they would look good in that tank (with 10 gal of water). What fish have you looked into? 1 Quote Link to comment

Clown79 Posted September 25, 2020 Share Posted September 25, 2020 I've personally seen blennies in shallow areas while snorkeling. About 10ft from the shore amongst rockwork. Will you be having liverock in this tank? Quote Link to comment
Tired Posted September 25, 2020 Share Posted September 25, 2020 If the tank is brackish, look into brackish-water fish and how people do mangrove setups. Fiddler crab don't live on pretty sand beaches like how people imagine the shoreline, they mostly live among mangroves. You would probably find blennies and gobies there, and they're likely not going to be very pretty colors, since they'd live in mud. If you could manage a decent amount of space for them, mollies can be acclimated to any reasonable salinity. I've personally seen fiddler crabs in sailfin molly habitat. They should have a tank longer than a 10gal is, so if you split up the 20gal in a way that provides plenty of length space, instead of just making half its length sand like some paludariums, sailfins should be OK. Make sure there are solid surfaces for them to pick algae off of. They probably won't go after your crabs. Quote Link to comment
Leo_ian Posted September 26, 2020 Author Share Posted September 26, 2020 ooh ok. I have seen people keep fiddlers in reef tanks before so it was just a consideration. are sally lightfoots a good option too? 10 hours ago, Clown79 said: I've personally seen blennies in shallow areas while snorkeling.

Tired Posted September 26, 2020 Share Posted September 26, 2020 Fiddlers don't actually do well in fully aquatic setups. They need a paludarium setup. I would look into whether any are full saltwater, I don't know. Sally lightfoots are a potential threat to fish. They venture out of the water now and then, but not much, so a paludarium's land space would be largely wasted on them. Better to just have a saltwater tank with one of those magnet rock shelf things as an island, if you could find a way for them to get up to it. Crabs can't climb glass. You should have live rock. It can actually be more important to your tank than straight-up water volume in terms of stability, because of all the bacteria it can host. You'll also need to figure out water movement, which is tricky in paludariums. Stagnant water doesn't work terribly well for most aquatic life. Quote Link to comment
Leo_ian Posted September 26, 2020 Author Share Posted September 26, 2020 Yea its a saltwater paludarium. I am getting a canister and hooking it up to two opposite ends of the tank so the sand can be moist. So sallies are off the list. Quote Link to comment
Tired Posted September 26, 2020 Share Posted September 26, 2020 Sallies should probably be off the list, yeah. You should really look up what kind of fiddler crab you can get, as in what species, and then find out what salinity they need. If you can't get a kind that likes full saltwater, you'd need to adjust things accordingly into a brackish tank. 2 Quote Link to comment

Tired Posted October 9, 2020 Share Posted October 9, 2020 A tang, in a tank with less than 20 gallons of water? Hell no. 1 Quote Link to comment
