Bottom Feeders for 23 Gallon Tank

I have a 90 litre (23 gallon) tank. I have:
- 4 dwarf gouramis;
- 3 guppies;
- 2 mollies;
- 2 swordtails.

I also had 3 julii cory's and 3 bronze cory's. However, 4 of them died and I am now left with only 1 bronze cory and 1 julii cory. They seem to have trouble adapting to my tank.

My water readings are as follows:
- Amonia: 0;
- Nitrite: 0;
- Nitrate: 0;
- Genreal Hardness: 16dH;
- Carbonate Hardness: 10dH;
- pH: 7.0;
- Chlorine: 0.8mg/l.

All my other fish are ok.

Can anyone offer advice on which bottom feeders would adapt best to those readings and the size of tank (I know a lot of bottom feeders grow huge!).

Thanks for any advice!

I had a pair of clown loaches in with some gouramis when I fist started my first 30 gallon I was told that they would get to big but they were some of the most beautiful fish that I have ever gotten and they are bottom feeders. Recently I also have gotten yo-yo loaches and they are quite comical but you need to keep them in a shoal of at least three, look into queen botia loaches those are also quite nice. The clowns are bery peaceful but also very finicky to the water conditions. the yo-yos have been known to put up a fight with my red tail shark and win :p

Loaches are lovely fish, but in the confines of a 23g tank your choices are very limited. All loaches must be in a group, minimum 3 if that is absolutely necessary due to space, but 5 is better for the fish, they have a very high social structure. The only species suitable for a 23g would be the two dwarfs, Yunnanilus cruciatus (Banded Dwarf Loach) or possibly Yashuhikotakia sidminthuki (the common dwarf loach), both are in our profiles (click on the shaded names). The former would be better but are more demanding of soft acidic water which with your livebearers I assume you do not have.

None of the other common species in Botia should be in a tank under 3 feet, and that only applies to maybe the Zebra, a 4-foot is minimum for most. Clown loaches are large-tank fish, 6-feet or more. This considers their attainable size but they grow quickly (if they are healthy in suitable tanks that is).

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]
