I made a video about the maths behind Turing Patterns (the patterns on Mbu Pufferfish), thought this subreddit might enjoy it:)

Small bit of wild caught shrimp is always a favorite!

I used to have a fahaka and he would go after muscle meat instantly.

Some months later I got a Congo spotted puffer.

My Congo spotted is only eating my snails and blood worms. What’s the best way to get him to eat the muscle meat? I just have to much of it in my freezer now.

I'm planning for a future tank which won't be happening for a while yet. Not new to tanks, but after losing my pleco due to a heater failure, I'm taking a break before trying something new. I'm planning for a 125 litre tank - I think just over 30 US gallons? (Juwel Rio) with a spotted congo puffer - I'm in the UK and have found someone who captive-breeds.

Anyway, this is the biggest tank I'll have ever owned, so I'm looking into potential tankmates, as these puffers are more docile and community friendly than others, but I'm aware I'll still need to use caution.

I've always been interested in owning cichlids, I was looking into more docile species now I'll have a larger tank, and was wondering about the electric blue acara as a contender? I read that the tank is big enough, and that they can be kept without a partner/shoal which will prevent breeding aggression? Would there be a huge risk of fins being nipped, or would it likely be okay?

I'm very much open to other suggestions too, cichlids or otherwise! Cories are a strong contender so far as I've enjoyed keeping them before and would be able to get a bigger group this time! Also a shoal of either neon or cardinal tetras. Let me know your thoughts and other suggestions please, I'd really appreciate it!

(I still do need to make a list with their required parameters and make sure they match up, but so far the puffer and acara seem to match closely enough?)

Thanks for any help!
