How to make fish grow faster?

Hi, i bought some 10 harlequin rasboras, but they are TOO small. about the size of a cardinal tetra...

They are gonna be in my 68 gallon asian tank, which has 12 Tiger barbs, they are small, but they are feisty, 6 checkered barbs, 6 gold barbs and 2 pearl gouramis.

Anyways, i've had them for 2 weeks already, but i don't know how fast these grow, i think they are smallish 1 1/2" - 2 "

I feed them tetra min flakes, tubifex cubes and artemia, i try to feed them several times a day...

What would you recommend? Thank you

These are not big fish to start. 1.5-2 inches max size. Frequent water changes and clean water. Blood Worms, mysis shrimp, and a quality flake or pellet.

Sounds to me like they're already adult-sized.

I don't know what's available to you in S. America, but feed them food that has high protein.

Feed them stuff that isn't just protein too. Nutrients will make them able to use the protein to grow healthily. But yes, beefheart. And vegetables. Vegetable protein. Nom... The darker the better; those carry more nutrients. Not like zukes

Ah, I understood the same as O_S.

In that case, daily water changes and feeding several times a day with a variety of foods (live would be ideal, but frozen and quality dried foods also works) is the best way to maximize growth.

Yup, my bad, i meant that that size is the supossed maximum growth. Sorry...

And yes at the time being, they are very small. Even smaller than my stimates, i would say 1/2" - 3/4" the largest i have...

Like i said, i feed them Tetra flake foods, artemia salina ( not live though) and tubifex cubes, several times a day, but well, i've never had luck with fish growing, and that 's why i'm asking what would you do

My opinion is they are not likely to do well in a tank with barbs. They like very peaceful tankmates.

I have approx two dozen Rasboras with a dozen black ruby barbs that have been doing well for around four months but I agree they would prolly prefer smaller less active tankmates.

You are going to want a better flake food. I'm fond of Hikari Micro Pellets; my fish gobble them up and stay in good shape even with them as a staple. New Life Spectrum Thera A is an excellent choice as part of the staple diet. Omega One, Ocean Nutrition, and Kens are good choices as well.

You should really consider hatching some baby brine shrimp. They are easy to hatch, and small fish LOVE them. They are pack-full of nutrition!

Frozen daphnia, bloodworms, and beefheart will give them a real boost. Spirulina is a good addition as well. Ken's has an awesome flake, but Hikari Algae Wafers will do.

A variety of good foods and nice clean water will go a long way with fish. They will be healthier and live better lives if they are fed right. Most of these things you can feed to all your fish, and they will all thank you for it with healthier, flashier colors!
