This past summer I kept my 20 african haps in an 8 foot kiddie pool. In about 4 months they put on almost an inch in length. As the nights cooled I was busy with work so I put off bringing them back indoors for the winter. So I would cover them at night with a bubblewrap thermal cover to avoid the water temp dropping below 62 deg. In the morning I would remove it. One morning I left for work and forgot to take it off. When I got back home my haps which I had nurtured all summer had been suffocated! After more than 30 years of keeping fish I remembered "fish need air!" Only a red zebra and electric blue survived out of the 20.
