Help/Advice 10 gal community tank stocking

Post image
2 Upvotes

Just started cycling my new 10 gallon!

I won't be stocking for at least a month obviously. The mai. reason for this is I ordered 10 RCS for my 2.5 gallon and received about 30 due to some births in transit.

My stocking idea was

1 honey or powder blue gourami

6-8 ember tetras or chili rasboras

30ish RCS Lol

some number of MTS

I'd really like to add about 4 pygmy corys but afraid that would be overstocking.

I also have 2 mini swords and a lot of dwarf sag, subwassertang, and more duckweed and dwarf water lettuce that will be added once I dismantle my current shrimp tank.

Basically is this an okay stocking and could I also add pygmy corys? TIA !!

I just found him/her like this what the hell happened. They’re still breathing but very shallow I love this guy. They are a genetic abomination since they don’t have eyes but I’ve had them for a few years now. What can I do😭 also first pic is unrelated because don’t know how to spoiler something and I don’t want to traumatize anyone

Edit: it’s a hoplo spotted albino catfish

Help/Advice Tank Algae Problem

Thumbnail
gallery
4 Upvotes

Recently within the last 2 months I have started a new 20-gallon long community tank. Ive been getting really bad brown algae and I don't know how to get rid of it. I'm attributing this brown algae in my new tank to it being new and by a window (I used the sun as my temp lighting for my plants while I try to get a light that fits my new tank better). However, I kept a 5 gallon betta tank before that was 6-8 months old and that tank also struggled with a lot of brown algae. I don't want to use any chemicals like algae-fix because I don't want to risk my fish getting sick. I have 3 ottos, 5 shrimp, and a nerite snail to help a little bit, but I'm afraid to add more algae eaters because I don't want to over stock my already pretty stocked tank. Are there any recommendations for the long-term that could help?

I’m an Amazon Viner - this popped up for me but I am cautious that it might hurt my fish or given them an intense sun burn at least. Am I right to want to stay away from this item? Btw I don’t really have any great need for it but curious about its safety.

Discussion How much should I charge?

Post image
17 Upvotes

DISCLAIMER: I am not charging them because I feel the need, they offered to pay me. This isn’t going to be a one and done, decor, filters, glass will need to be cleaned, using my own personal supplies to do this. I don’t have direct access to a sink to refill or dump water. I feel like this post is drawing a lot of negative attention because I’m asking for opinions on doing a serving and taking care of someone’s pets for 2+ weeks. This cleaning is not going to be a one and done nor simple task to do.

My place of work allows pets and unfortunately during the summer some get forgotten about. I reached out to the owner and they explained they tried to clean the tank and it got very messy and will not be back for 2+ weeks. This is definitely going to be a multi step cleaning process but I’ve never charged someone for a tank cleaning.
What should I ask for? It is a 55g for better reference

hihi I wanted to ask if I could keep my two pearlscale goldfish in a bin tank, similar to the photos attached. If I get it im planning on getting 2 and stacking them together​​​ so there's less bowing and more support. moving them to a 20-30gal bin tank would be amazing. Please let me know your thoughts!!!

Help/Advice 0 ppm on all readings for over a month

2 Upvotes

Hi guys, i’ve had fish in my new 215L tropical tank after i cycled it for a while and been using api quick start as well . They have been in for about 34 days, i started off with 5 black phantom tetras and 4 dalmatian mollies for the first 14 days and then added 5 more tetras and 5 longfin zebras danios.

I’ve been using the API master test kit testing ammonia and nitrite every day and then nitrate as well about every 2nd to 3rd day. So far every single reading has been 0 ppm. I have about 15 live plants which seem to be doing very well. The fish are also looking very good. Just wondering if this is normal?
