I am thinking of performing a substrate change from black sand to white sand in my 20 gallon, but also i think that my 3 yoyo loaches need a bigger tank.
I've read several articles saying that a 20 gallon is the limit and a max of 3 in there should be ok but i know that they'd love a bigger tank.
I was thinking of re-designing my tank to hopefully make it as nice to live in for them as possible and because i want to do a substrate change i could do both at the same time.
By re-designing the tank i mean make it as spacious as possible with plenty of hiding places and nooks that they can get in and out of etc...
Another option would be to put all 3 in my bigger 25-30 gallon (3 footer) and put the cories that would be going into the 3 footer in my 20 gallon.
This would make the most sense as 3-4 panda cories would fit much better in the 20 gallon than 3 yoyo's.
Also if i can completely re-design my 20 gallon in preperation for some cories then it will make me excited about that one aswell.
I dont really know what to do, i was set on re-designing the 20 gallon for the loaches but during the typing of this post i'm in-between ideas.
If anything i've changed my mind slightly and think i should put the yoyo's in the 3 foot tank.
