fish compatibility

Hi all ! I saw this beautiful fish that i’ve never seen at any of the aquarium stores I frequent before and it caught my eye ! I was wondering: is it more of an advanced fish ? i’m about 7 months in to marine aquarium keeping and have done tons of research, but mostly on a lot of the basics. I...

Hello All, I am looking to add a second tang to my 125G reef tank. I have a small BIOTA yellow tang currently that’s been with me for about four months. He’s been a great fish and been a model tank mate. I’ve always wanted a convict tang and was thinking of purchasing one to add to my tank...

So I have a yellow spotted scorpionfish (about 1”) and saw a fu Manchu lionfish (about 1.5”-2”?) for sale, I was wondering if they would be okay in the same tank at their sizes or should I place the lion in a separate tank. My scorpionfish eats large Amphipods, but I also have saltwater grass...

Hi, I have one purple fire fish in my 24 nano and want to add a helfrichi fire fish as well, but I don’t know if they are compatible in a smaller tank

I would like to know if these two fish would get along in an evo 13.5? I know the blenny is mostly vegetarian while the goby is mainly carnivorous but they both dwell on the bottom. The Hector's goby is already in the tank and found his burrow. Would like to add a tailspot blenny if they are...

Hi guys. I have a 180 gallon mixed reef. I was hoping for some advice about mixing and introducing some wrasse, dither fish and bottom dwellers to my tank. Esentially anything small that will help add a bit of a sense of scale and colour when compared to my tangs - which I realise I have a lot...

I have a new(er) 32gal nano and things were good with a 6-line, blue chromis and green chromis. The 6-line gets along with everyone and the green chromis was always the dominant one between the blue and green. long story short, I recently added a bubble tip anemone and a “captive born” O...

I've had a Four-Line Cleaner Wrasse for a couples of months now. He doesn't really bother anyone at all. Whenever I add a new fish he just leaves them alone. I would like to get a pair of Possum Wrasse. I have a Red Sea Reefer 350 so it would be enough space for them but I just want to make sure...

Hi, I was have a 30 gallon set up. With a six line wrasse and a canary blenny. I really have my heart set on a dragonet but don’t wanna make that purchase if they don’t get along. Would they be peaceful if I add one? Thanks In advance!

Hi R2R community. I have attempted to search, but can't find anything that covers my question with my inhabitants. I recently got a Watchman Goby and would love to get him a friend. I've read a ton about Tiger Snapping Shrimp but am truly uncertain if it will fare well in my tank. Please...

Hi All, I have a 24 cal cube, looking to keep LPS ands softies along with fish. I currently have 2 Ocellaris clownfish and would like to add in the future (in order of preference) helfrichi firefish Diamond Goby Pistol Shirmp Bangii Cardinal (2?) Would this be okay in regards to compatibly...

Noob here. I’m doing my fish planning while I wait for my tank to arrive this week. I want to make sure I have decided on my livestock so I can be sure to take their habitats into consideration when I build my rock formation and start cycling my tank. Getting the 32.5 gallon Fluval Flex and...
