It's a very skinny gibby
I'm sure he'll be better in no time though![]()
It's possible they can reach 24" apparently, but the norm is about 18", but TBH if he's been badly cared for in the past - it's unlikely he'll get that big. I'd say he'll reach 15" or so, but who knows - it's always best to prepare for the worst...erm...if you get me. You need a 5 x 2 x 2ft tank for a gibby really, obviously the smaller they are the less you could get away with - but the bigger the better as he may have a growth spurt now he's being cared for properly.
Gibbies are omnis so veggies, good wafers, shrimp/prawns once a week, catfish pellets now and again...that kind of thing.
And Hawkins wasn't actually that huge for a gibby, he was only 15" - had to rehome him as our tank was too small for him to move about it (6ft x 2ft x 18"). It was the 18" bit that did it - had we had the 6 x 2 x 2ft at that point, we'd have kept him![]()
