Purchased 4 clown loaches today... couldn't pass up the sale and have been wanting to start a clown loach tank for a while. As they had just come into the store today, the owner strongly recommended quarantining them for 2 weeks before adding to my tank. I have them in a 10G right now with a couple caves for them and with 3 zebra danios as dither fish. My regular tank is a 20G long, stocked with a school of 10 harlequin rasboras and a timid pictus catfish of about 4" that more often runs away from the rasboras than considers eating them (so that's not a problem). It has an aquaclear 30. I'm planning on putting the clowns in the 20G long, and I know that's not enough space for them long-term. I'm just curious what the experts here think is too long to keep them in the 20. They are about 1.5-2" long at present. I'm hoping to keep them in the 20G long for about 6 months while I put aside some money / make space for either a 40G long or a 55. Thoughts? Also, what does everyone feed their clowns? Right now I am giving them the Hikari frozen bloodworms and they are eating (yay!) but I want to vary their diet. Thanks in advance all!
