Let’s say I buy an all blue guppy from a breeder that is very careful to keep the line as pure as can be, and then buy, say, a gold guppy from a similar minded breeder. My question is, when they breed, will the offspring be A) a greenish color from the two colors combining. B) some blue offspring and some gold offspring. C) blue AND gold. D) something else.

I know I learned about genetics, but it’s been so long since I’ve used that knowledge (middle school if I had to guess), that I’ve completely forgotten.

I fish in a local pond and usually the pumpkinseeds have vibrant coloration but today i caught 2 and both had a dull coloration, is it normal? Dont worry, this lil guy was alr and had a safe release

I inherited my grandparents fish + tank and trying to find out what this guy is so I can make sure to have the water quality where it needs to be for him

I have an Oscar about 1.5 inches in length can I add a peacock cichlid to the tank? It’s a custom 130 gallon tank.

I know goldfish rainbow shark Red tail shark Koi nothing else

I’m thinking about getting a 55 gallon tank and whole new setup. I need ideas for what kinds of fish to put in my freshwater tank when I get it

bob the salmon, he can do it!

Bad photos sorry.

I was gifted a black ghost knifefish; a fish I’d been dreaming about for YEARS. Had this guy for 6 months. Did a water change two days ago and everything was/is exactly where it needs to be. Fed him the usual amount this morning and watched him swim about for a bit, went out for a job interview, came home, and he was gone. I am so unbelievably sad because I don’t understand what happened. The last few months have really sucked for me and this is just the icing on the cake 😥

This has happened twice already and I don't know what to do.
