5 Missing Fish

I have a 29 gal tank with 20 live bearers, 6 female betas, 2 Gold Dojo's, 1 Chinese Algae Eater. They all got along beautifully for the last 60 days. Wednesday my water was so green with algae that I bought a new Fluval 405 and connected it. Friday I realized the 405 probably won't remove algae so I did a 50% water change. After the water change I found that 4 of my female betas and 1 Gold Dojo are missing. I tore the 405 apart and did not find even the smallest spec of a dead fish or dojo. My water change hose has a screen so they did not get sucked up during the water change. I always poor the old water into the toilet very slowly just to be safe. I'm really bummed. My betas were the prettiest fish in the tank and I love my Dojo with that cute face that looks like a baby seal. Did my Chinese Algae Eater eat them? He is the newest member of the tank.

Have you checked actually in the pipes of the filter? If theres no guard on the intake it is possible! What size is the algae eater? They would to my knowledge on try and eat fish smaller than them selves. Good luck fnding your fishes

Welcome to Tropical Fish Keeping forum.

You have some problems with the fish in this tank, and these are most likely contributing to the fish deaths.

First, a 29g is not sufficient space for the dojo loaches or the Chinese Algae Eater. Nor for 20 livebearers unless these are small fry or something. So this is going to cause stress on the various fish, and that leads to other problems.

I would get rid of the CAE any way you can. As it matures, this fish can get quite nasty. More info in the profile.

The dojo loach needs much cooler water than the livebearers, plus they grow large (can get up to a foot) and in insufficient space they will not develop properly as they grow, again causing stress and internal issues. And they are predatory toward small fish.

Our profiles are under the second heading from the left in the blue bar across the top of the page. Names that shade can be clicked to see that profile. Please check them.

Now, having said all that, any dead fish is likely to be very quickly devoured by the CAE and the loaches.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
