The only reason I haven't said much else is cause I don't know the fish well or the tank its going in too well but I will say that I'm happy for you. I'm glad you are taking your time and trying to make sure its the right decision and not just handing it off.
lol no worries, I don't know the fish well either!
Yeah, I wanted to find someone suitable for him, and figured he could stay in the 22g QT alone until the right place came along, or go to the store as a last resort, since I checked they'd be willing to take him before agreeing to get them! One person who responded to my ad seemed keen but when I asked about their set up, they wanted to put him in their Pick 'n Mix 20g tank... with two yoyo loaches, a clown loach (!) cories, a plec, endlers and tetra There were other fish too, but I forget what else they said. Wildly overstocked with completely unsuitable fish for him anyway. I said no, obviously!
I know my LFS is great, and would likely find a suitable home for him. But it would still be more stress for the rainbow to be moved and have to adjust to the store, then who knows how long to find a home for him and if it would turn out to be a good one. All of the adopted fish have been through enough already I think, so I'd much prefer to find his permanent home that he can go to straight to from here.
I wish I had endless tank space too
Haha, it's the dream for all of us, right? I think that's why a lot of fish youtubers go into it! Like MD fishtanks. He admits that he's newer to the hobby, but has a talent for scaping that makes his channel very watchable, and he has the personality to pull it off as well. He went from having a few beautifully scaped tank in a shed in his garden, to a large studio and sponsorships from places like Tropica, meaning he gets his plants for free, plus other things from other sponsors. Then can expand to a much larger fishroom/studio, needing new content means frequently creating new set ups, sponsorships and channel income winds up not only paying for the hobby, but also enough to live on! Dream come true really!
I'm too weird and shy to attempt anything like that, I hate cameras, lol. But I can admire the hustle and see how it's meant he can have any fish he wants now!
