Aquarium owners worry about fish compatibility

“I’m getting a tank in a few months and I’m planning the stocking, so far my plan is 9 clown kilifish 6 sparkling gourami 6 otos some shrimp amano and 9 cpd but I want to change the cpd but idk what to change them to im looking for a active mid level fish that schools and won’t bother any of the other fish and is less or equal to 2.5 inches max and not like 20 a fish (CAD) any ideas are appreciated submitted by /u/Ok_Top6537 [link] [comments]”

“I constantly see people warning never to mix Black Skirt Tetras with Angelfish due to fin nipping, but my setup is doing amazing with zero issues. I introduced a medium Marble Angel named Oslo to my established school of 8 black skirts in a 35 gallon tank, and they are completely peaceful. It works perfectly because keeping a full school of 8 tetras keeps their aggression focused on their own internal pecking order instead of other fish. Plus, introducing a sturdy, medium sized angel rather than”

“I currently have 3 sparkling gourami in a 20 long. I know neocaridina shrimp is risky with them but I was wondering if anyone had any insight to how they were with Amano shrimp. There are no other fish in the tank but I will be adding Pygmy Cory and rummynose rasbora, as well as 2 more female gourami when my LFS gets more in. submitted by /u/Thrashing_Tigress88 [link] [comments]”

“Looking for advice on which community fish to stock my 40 gallon breeder with. The tank has been running for a little over 4 months and is currently stocked with my lower quality neocaridina shrimp. This is what I’m thinking currently: 15 to 20 green neon tetras 8 albino corydoras 8 corydoras of a different variety 1 honey gourami 3 nerite snails + however many neocaridina shrimp How’s the bioload? If I wanted a second algae eater, could I also do a few amanos without it being overstocked?”

“Hello! I was sold these two Gouramis last week for my 20g tall. The owner of my LFS assured me that they should be in pairs and will do well together. But is this fighting/harassing? It doesn’t happen all the time, most of the time they stay separate. Also can anyone tell me if they’re both male? It seems they are which I’m assuming could be the cause of this. submitted by /u/Socialeprechaun [link] [comments]”

I have 2 white skirt tetras and 2 glo tetras (I have now also realized they need to be in larger groups.) I recently bought fancy male guppies in a group of 5 and off the bat I noticed that one of my glo tetras was starting to chase them around.

“I’m setting up a 10-gallon freshwater tank and was thinking about doing a small group of pygmy corydoras with Neocaridina/cherry shrimp. I was considering around 6–8 pygmy corys and starting with about 10 shrimp . The tank will have driftwood, rocks, plants, and a filter with a pre-filter sponge, and I’ll make sure it’s fully cycled before adding anything. Would this stocking level work well in a 10 gallon long-term? Do pygmy corys generally leave adult shrimp and shrimplets alone, or should I e”

The main reason being I want to put more fish in with her, I used to have neon tetras with my last betta, but they had to be separated due to fin nipping so I’m not taking the chance with them.

It's home to a very chill young male apistogramma borellii. My question is can I perhaps add a female for him or is this asking for trouble? I'm fairly sure he'd be fine on his own and I'm wondering if I'm pushing the tank stocking wise. His tankmates are a bristlenose, 6 WW tetra, 8 juvenile neon gold barbs and 6 rosy barbs.”

“I really want to have some neocardinias and a betta. I know that many bettas will just devour them, but sometimes can be okay and won’t pay any interest to them. I’ve seen people suggest to get a few shrimp and let them get used to the tank before you add the betta, so they know the hiding places. I just obviously don’t want to do that and then he eats all the shrimp. I know nothing is guaranteed but is there a way to see the bettas temperance in the shop before I buy one? I have bought neither”
