1, Luohan fish tank is at least 80cm (length) *40cm (width) *60cm (height) above, and fish that are too small in the tank will never grow up and may even die!

2. Is the bought fish crushed? A fish that has been crushed too hard has become an old fish and won't grow up!

3, feeding, whether it is possible to feed regularly, regularly, quantitatively, and a little bit, but we can't let there be unfinished feed in the tank, so as not to pollute the water quality!

4. How old is your fish now? You'd better look at the picture! Generally, arhat fish can be divided into four periods.

Seedling stage: from egg birth to about 2cm.

Irrigation period: 2 cm to 10 cm.

Sub-growth stage: about10cm to 25cm.

Adult fish period: about 25 cm, 40 cm. According to the species and breeding environment of arhat fish, the size of adult fish will be different!

I suggest you go to the professional forum of arhat fish to learn!
