Aquarium owners worry about fish compatibility

“3 months into my 90P (90×45×45cm) and currently have 40 cardinal tetras. I’m thinking about adding a centrepiece fish. Has anyone kept Pearl Gourami with cardinal tetras in a tank this size? Would love to hear your experiences — temperament, compatibility, and whether you think it would suit the tank. Or would you recommend a different centrepiece fish? submitted by /u/Gullible-Hat2030 [link] [comments]”

“I've been wondering if it's possible to build a community tank where both hillstream loaches and pygmy corydoras can breed.

“My tank is 29G with around 12 zebra danios, 5 platys, 1 clown pleco, 4 assasin snails and a bladder snail infestation. The platys I got like a month ago all at the same time. The bully is a boy but I am not sure the genders of the others because I cant really tell them apart. I have seen him chase a lot, and recently, the only other green later platy came out for the first time in a few days and was totally fin nipped/beat up. That platy hides all the time now. So I got this box to separate them”

“This is my well planted 10 gallon that currently hold 5 Pygmy Cories , 6 ember tetras, and a bunch of shrimp and ramshorns.

My current stock is: 10 Spotted Blue-Eye Rainbowfish 10 Flame Tetras About 6 Amano shrimp Around 12–13 adult cherry shrimp, plus quite a few babies My main concern is the shrimp. Would a Pearl Gourami likely devastate my cherry shrimp population, especially the babies? I’ve read a lot of mixed experiences—some people say their Pearl Gouram”

“55 gallon community tank. For now we’re considering Neon tetras, roseline sharks, Cory catfish, zebra danios, plecos, maybe shrimp. My wife is set on one or two Gouramis she loves the color, but I’ve read conflicting views on whether or not they’re too aggressive for a community tank or not. submitted by /u/Major_Tom37 [link] [comments]”

I have cherry shrimp, a Siamese algae eater, and soon a shoal of 20 neon green tetras. It's pretty well planted and I typically have two sponge filters running, one is seeding a quarantine tank for the new neon greens.

“Hi all! I have a 5 gallon freshwater aquarium with 3 small feeder guppies and a new snail I bought recently. For some reason, the feeder guppies keep “resting” upon the snail.

“hello iv been fish keeping since april this year and recently my betta passed away a week ago from illnesses. i’m ready to add new fish this tank hopefully Friday! right now all i have is 7 corydoras in this tank and nothing else, i was thinking on getting 2-3 honey gouramis (2 female 1 male recommended from what iv seen) but i was wondering what else i could put in this tank to liven it up? or if the gouramis will be ok with my corydoras if this tank size is not ok for gouramis let me know !! &”

“I have 6 longfin danios in a tank around 20 gallons and asked the store about algae eaters that are good with them, and they gave me 2 Chinese algae eaters. I didn't know much about them and trusted this would work until I saw on Reddit and online how aggressive they can be. I am unsure if this combination means I have to go back and return these fish. I would like to know what you guys recommend I should do and if I sdo swap them out, which are better algae eaters for this tank with the dan”

“I have a 60 gal breeder and added 10 bloodfin tetras today. I have wanted to get forktail rainbowfish as well. Forktails are top water and bloodfins are top to mid level water. Does anyone house these together that can give me some insight into their compatibility? Both are same size, same active swimming behavior, and same active feeding behavior. It looks good on paper, but I'd rather trust real world experience. submitted by /u/ifitfitsitshipz [link] [comments]”

“Hello, this is the question. The aquarium is 4 months old and only had ever had ramshorns and bladders. It's 60L. Can I comfortably fit the two species? If I can, is it better to go with 8 and 8, 10 and 10, 10 and 8, 8 and 10?? Idk My routine is changing ~25-30% of water every 10 days but I can shorten that to every week if it's too stocked. Would they be comfy together? Can they eat the same identical stuff? Should I get one species before the other? Thank you :) Ps: I keep the lights o”

“Hi there guys!! I’m just setting up a new 48 gallon heavily planted tank, stocking list plan so far: - Kuhli loaches - Forktail loach (if I’m lucky enough to find one) - Bristlenose pleco - Nerite snails - Some sort of small schooling fish such as tetras or raspboras, haven’t decided on which exact kind What I can’t decide on is a ‘feature’ fish, originally I was planning on adding a giant betta as I absolutely love their personalities, but I’ve been noticing a lot of people saying their gourami”
